test: unskip snapshot reproducibility test

[joyeecheung]

See if the v8 14.6 upgrade has fixed it.

On a side note, debian will require reproducible builds in their packages https://lists.debian.org/debian-devel-announce/2026/05/msg00001.html

The reproducibility test job hasn't been showing any problems, although it's still configured to build with gcc. Have you been seeing problems pre-14.6?
Either way I'm happy to have this test unskipped :-)
