Fix PMC publishing script and mapping

[SteveL-MSFT]

PR Summary

• disable color, appears that NO_COLOR is no longer working
• package name should just be dsc as the preview is part of the version
• fix mapping for rpm which should be a period between version and arch

[Copilot]

Pull request overview

This PR updates the EV2 publishing workflow for DSC Linux packages uploaded to packages.microsoft.com, correcting RPM filename mapping and aligning the published package name with the current versioning scheme while attempting to suppress colored output in logs.

Changes:

• Update RPM PackageFormat in the PMC mapping to use the correct .arch separator (e.g., -1.x86_64.rpm).
• Adjust the publishing script to force package name to dsc (preview/stable distinction is now carried in the version).
• Switch from NO_COLOR to PowerShell output rendering controls to reduce ANSI color output in logs.

• $PSStyle.OutputRendering is not available in older pwsh versions; assigning it unconditionally can throw (e.g., when $PSStyle is $null) and abort the EV2 deployment. Guard this assignment so the script still runs on older PowerShell while keeping NO_COLOR as a fallback.

$PSStyle.OutputRendering = 'PlainText'

• $PSStyle.OutputRendering is set unconditionally. $PSStyle (and/or the OutputRendering property) is not available in older pwsh versions, so this line can throw at script start and fail the EV2 run. Guard the assignment so it only runs when supported.

• Get-PackageObjects mutates the function parameter $ReleaseVersion inside the foreach loop when handling RPM. Because the mapping lists RPM packages before DEB packages, this will also change the version string used to construct subsequent DEB filenames (e.g., preview versions will incorrectly use '~' instead of '-'), causing package path lookup failures.

        if ($pkg.PackageFormat.EndsWith('.rpm')) {
            # RPM requires no dashes in the version string, so replace any dashes with tildes
            $ReleaseVersion = $ReleaseVersion.Replace('-', '~')
        }

• $PSStyle.OutputRendering is assigned unconditionally. On older PowerShell versions where $PSStyle (or the OutputRendering property) isn't available, this will throw and can fail the EV2 deployment script early. Guard the assignment based on the PowerShell version so the script still runs when OutputRendering isn't supported.

$PSStyle.OutputRendering = 'PlainText'

• In the catch block, Write-Error -ErrorAction Stop ... raises a new terminating error, so return 1 will never execute (the script will terminate with the new error instead). If the intent is to log the detailed error and exit with a non-zero code, write the error without -ErrorAction Stop and then return 1.

} catch {
    Write-Error -ErrorAction Stop (Get-Error | Out-String)
    return 1
}

• $PSStyle.OutputRendering is only available in PowerShell 7.2+. This script runs under pwsh, but if EV2 uses an older version (e.g., 7.0/7.1), assigning OutputRendering will throw and abort the rollout. Guard this assignment so older PowerShell versions still run with NO_COLOR/TERM fallbacks.

$env:NO_COLOR = 1
$env:TERM = 'dumb'
$PSStyle.OutputRendering = 'PlainText'

• In this catch block, Write-Error -ErrorAction Stop throws a terminating error, so the following return 1 is unreachable. If the goal is a non-zero process exit code, prefer writing the error and using exit 1 explicitly (or remove the unreachable return).

    Write-Error -ErrorAction Stop (Get-Error | Out-String)
    return 1

• $PSStyle.OutputRendering is assigned unconditionally. On pwsh versions where $PSStyle doesn't exist (or doesn't expose OutputRendering), this line will throw and stop the EV2 run before any publishing happens. Guard the assignment so the script still runs when PSStyle isn't available.

• $PSStyle is not guaranteed to be present in all pwsh versions (it was introduced later than basic pwsh support). Assigning $PSStyle.OutputRendering unconditionally can throw ("You cannot call a method on a null-valued expression") and stop the rollout before any work is done. Guard the assignment so older pwsh versions still run with NO_COLOR/TERM fallbacks.

$PSStyle.OutputRendering = 'PlainText'

• This script is launched via pwsh ./Run/Run.ps1 (see UploadLinux.Rollout.json), so return 1/return 0 at script scope does not reliably set the process exit code. As a result, EV2 may treat failures as success. Use exit to set the pwsh process exit code. Also, Get-Error is not available in all pwsh versions; re-emitting the current error record is more compatible.
