Translators are not listed as contributors

Hello.

Right now, Peter pushes all new changes from the pgtranslation repo to
the main one. And I'm in no way accusing Peter of anything. He is
already doing a lot by handling all this stuff. The commit message
looks like:
------
Translation updates
Source-Git-URL: https://git.postgresql.org/git/pgtranslation/messages.git
Source-Git-Hash: fcf4cea0a0730cdd7f5da35160ab1c745212768f
------

If we check other commit messages to the main repo, for example just
the latest I see:
------
postgres_fdw: Adjust warning message in statistics import.
The previous warning message when falling back to sampling in a certain
case failed to properly mention the reason for that.

Also, for clarity, rewrite a comment about the fallback and add a note
about it to postgres-fdw.sgml.

Follow-up to commit 6a85715.

The difference here disturbs me. I noticed the situation a long time
ago but had never started a discussion.

What triggered me this time is the situation with the pt_BR language
in particular. For those of you who are not aware, pt_BR could've not
make it into the Postgres 19 release due to a low level of translated
strings (<80%). On the Crowdin platform [1], we have an active
community working hard on exactly this language. So I pushed all
strings done by them, and now pt_BR qualifies with 85%. In practice,
those nine translators saved the language from exclusion. But no one
ever hears about them or about all other translators because we treat
this as a non-important non-committer job.

I'm sure that all translators who participated in release translations
must be listed as contributors to the release. It's not fair to ignore
all the people and efforts they committed. This is especially true for
people outside of our community, who contributed just because they
love open-source and are committed to it.

Something like this would be cool:
------
Translation updates
Source-Git-URL: https://git.postgresql.org/git/pgtranslation/messages.git
Source-Git-Hash: fcf4cea0a0730cdd7f5da35160ab1c745212768f

Translators: John Johnson john(at)john(dot)son, Will Smith, ....
------

This also forces people to list translators in pgtranslation repo commits.
