Short description

The bindata project just released a new 3.0 major version, but we are currently pinned to an old ruby_smb release, which depends on this gem.

I opened this PR before really looking at OpenBolt, but now that I examine the state of automated tests over in that repo I can see that bindata 3.0 is not compatible:

/opt/hostedtoolcache/Ruby/3.2.11/x64/bin/ruby -I/home/runner/work/openbolt/openbolt/vendor/bundle/ruby/3.2.0/gems/rspec-core-3.13.6/lib:/home/runner/work/openbolt/openbolt/vendor/bundle/ruby/3.2.0/gems/rspec-support-3.13.7/lib /home/runner/work/openbolt/openbolt/vendor/bundle/ruby/3.2.0/gems/rspec-core-3.13.6/exe/rspec --pattern spec/integration/\*\*/\*_spec.rb  --exclude-pattern spec/integration/transport/\* --tag apply --tag ~docker --tag ~winrm

An error occurred while loading spec_helper.
