feat!: remove Transifex calls for FC-0012 - OEP-58

[OmarIthawi]

Breaking change!

This change breaks the Jenkins transifex integration which has been deprecated in favor of the new GitHub Transifex App integration as part of OEP-58.

Changes

• Removes direct use of tx pull and tx push commands
• Remove source and language translations from the repositories, hence no .po or .mo files will be committed into the repos
• Remove Transifex related Makefile targets and configuration files
• Remove all unneeded mentions of Transifex
• Clean up paver i18n_* obsolete commands

TODO

• Test locally on devstack before pull_translations

Screenshot for Arabic language without translations

• Test locally on devstack after pull_translations

Screenshot for Arabic with translations

References

This contribution is part of the FC-0012 project which is sparked by the Translation Infrastructure update OEP-58.

This line is causing some problems -- it deletes any virtualenv that's maintained inside the repo (.venv-3.8/ in my case) as well as the Open_edX.egg-info/ created when installing base requirements. The former causes the command to fail entirely, and the latter produces the following error:

RuntimeError: Model class openedx.core.djangoapps.content_libraries.models.ContentLibrary doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
make[1]: *** [Makefile:52: pull_xblock_translations] Error 1

Can we use a different command? Or is this even needed at all. It seems to me that a git pull should remove the files just fine.

[timmc-edx]

It appears that if one of the path arguments to git clean doesn't exist and contains a globbing character (e.g. */static/js/xblock.v1-i18n/) then the command also removes some things outside of the given paths.

@timmc-edx sorry about that. I don't fully understand why git clean is behaving like this, so I've gone and refactored the command to be more explicit and safe:

• fix: avoid removing Open_edX.egg-info/ with git clean | FC-0012 #34380
