Updated translations don't show in MuseScore

Seems the corresponding cron job (for https://github.com/musescore/tx2s3) on Travis CI (run every 15 minutes, see https://travis-ci.org/github/musescore/tx2s3/builds) fails due to missing or wrong logon credentials to Transifex:

$ ./tx2s3.sh
Updating translation on s3...
tx ERROR: Authorization Required
tx ERROR: 
Error: Authentication failed. Please make sure your credentials are valid.
For more information, visit:
https://docs.transifex.com/client/client-configuration#-transifexrc.

It doesn't really report that failure as such though, which is another bug here, it just fails silently:

The command "./tx2s3.sh" exited with 0.

so Travis CI marks the jobs as successfully finished.
No idea how long that is going on already.

I guess we may want to move the cron job from Travis to a GitHub action,

on:
  schedule:
    # * is a special character in YAML so you have to quote this string
    - cron:  '*/15 * * * *'

See https://docs.github.com/en/free-pro-team@latest/actions/reference/workf…

It seems the translation updates have not been pulled/updated since 17th September 2020 (for gl) or 3rd October 2020 (for en_US), the latest dates I could find. Exact details might be seen in http://extensions.musescore.org/3.5/languages/ to those with sufficient privileges

Seems to be working again

The tx2s3 jobs are running again, but still don't offer updated translations in the MuseScore dialog apparently

https://github.com/musescore/MuseScore/pull/6723

PR got merged, but issue seems to persist

Should be fixed with PR https://github.com/musescore/MuseScore/pull/7159

It is (not) happening again!

and fixed again

Well, not quite. It still works and still is fixed, i.e. updated translations from Transifex to show in MuseScore.
The Sicilianu translation request though is not, see #312513: Sicilian Translation
