Added action to prevent changing msgid (#1351)
See discussion in #1344.

This checks that all `.po` files changed in pull requests either contain
changes in POT-Creation-Date (i.e. are run by the specific tool which
should change msgid's), or don't change msgid's (by checking that each
line changed is NOT between msgid and msgstr)

I have tested this on my fork, see [valid
changes](https://github.com/noamzaks/comprehensive-rust/pull/1/files)
where the action passes, and [invalid
changes](https://github.com/noamzaks/comprehensive-rust/pull/2/files)
where it doesn't.

The action also has output for failing/passing:

[passing](https://github.com/noamzaks/comprehensive-rust/actions/runs/6488171290/job/17620037473?pr=1)

[failing](https://github.com/noamzaks/comprehensive-rust/actions/runs/6488175171/job/17620050716?pr=2)
