chore: fix JavaScript lint errors (issue #13209)

[mantrapatel05]

Description

Fixed two lint errors:

• Replaced new Array(n) with an array literal + .push() in to_array.js (stdlib/no-new-array)
• Removed a stray blank line between two require statements in dsymv's test.ndarray.js (stdlib/no-empty-lines-between-requires)

Note: I noticed #13210 already addresses this same issue, but it appears to have stalled — the contributing-guidelines check has been failing for a month with no maintainer review. Opening this as an alternative in case that one needs to be superseded or closed.
