feat(lang): update messages.po(t) and add missing German translations

[hbruch]

SUMMARY

This PR

• updates messages.pot file and derived language dependent *.po files (generated via ./scripts/babel_update.sh)
• adds missing German translations to the .../de/.../messages.po file

NOTE: this PR does not (yet) include the messages.json files, as I'm hesitant to include them with this PR. They could be generated in the build process and probably should not be checked in anyway. Please let me know, if the de/.../messages.json or all languages files should be part of this PR.

NOTE FURTHER, that there remain some not-yet-localized messages, e.g. the last-modified times in the following screen shot, which are not created localized via helpers.py/changed_on_humanized and created_on_humanized

CI is failing, can you please address?

Babel generates unnecessary empty lines just before EOF (see python-babel/babel#799). For now, I removed them manually.

Either a comment should be added to CONTRIBUTING.md or scripts/update_babel.sh be enhanced to chop off this EOF newline, as long as the above cited issue is not fixed.

[nytai]

messages.json should be part of this PR FYI.

That sounds reasonable, can you do one of those?

This PR now

• updates messages.pot file and derived language dependent *.po files (generated via ./scripts/babel_update.sh), as well as messages.json files (generated via ./scripts/po2json.sh)
• adds missing German translations to the .../de/.../messages.po file
• fixes wrongly named pt/messages.po file
• in .scripts/babel_update.sh chops off at EOF for po/pot files

@nytai I see the latest failing tests as not related to my changes. Could you confirm, please? In case tests are flaky, is there anything which could be done about this?

[hbruch]

I'm currently a bit disappointed by flaky tests blocking review/merging. Please correct me, if I'm wrong @rusackas, but the failing test is not related to this PR, is it?

[villebro]

@hbruch I restarted the flaked tests, 🤞 they'll pass this time

[rusackas]

Restarted the python integration tests... we'll get this thing through!!!

[rusackas]

Was the extra line causing a problem (e.g. linting issues) or is this just cleanup to feel good about things? Only asking because the other solution might be to tweak the linting rule for these files. This seems fine, I'm just curious. ¯\_(ツ)_/¯

[hbruch]

The duplicated empty line was reported by a linting rule, indeed.
