AVRO-4239: fix Perl porting's lack of version number

[alivraghi]

What is the purpose of the change

Starting with v1.11.4, the Perl porting fails to dinamically set the $VERSION variable when installing from CPAN or from .tar.gz.

Verifying this change

Reviewed the dist build process to make available VERSION.txt file in the .tar.gz dist.

@RyanSkraba This seems to be needed for 1.12.next

Is this also needed for 1.13?

To me this change looks like a way to make VERSION.txt available for the Perl module after distribution. If my guess is correct, I think we'll want apply this change to main as well.

Yes; the goal is to ensure VERSION.txt is available for the Perl module within the distribution file.

This adjustment needs to be applied to both the 1.12 and 1.13 branches, as well as the main branch. Please let me know if you would like me to submit a separate pull request for the 1.13 branch.
