Fix version matching regex in Deploy.ps1 (#2202)

The Deploy workflow is failing because the regex for matching
\defaultBcContainerHelperVersion\ requires a trailing comment (\# ...\),
but [AL-Go-Helper.ps1](Actions/AL-Go-Helper.ps1#L30) no longer has a
comment on that line.

This fix makes the trailing comment optional in the regex pattern.
