Fundamentally improve German translations

[veprogames]

PR Description:

poedit and archinstall now report 100% translation rate for German. I added tr() invocations in some places and adjusted the locale generation script to properly detect them (I didn't work for me before).

Tests and Checks

• I have tested the TUI roughly
  

But there's a problem: Some translations are not picked up, for example "No audio server". I didn't figure out why, did I overlook something obvious? I ran the locale generation script before committing and the .mo file was changed.

Some translations also had a different amount of {}. I don't know if I broke something without noticing.

Should I regenerate all languages because the .pot changed?

Is it because of this?

archinstall/archinstall/tui/help.py

Lines 33 to 36 in 9bb7ced

	# the groups needs to be classmethods not static methods
	# because they rely on the DeferredTranslation setup first;
	# if they are static methods, they will be called before the
	# translation setup is done

If so, I'd remove the tr calls from Enum values

I'm not sure we should translate this, it's the actual value stored in the mirror configuration

Regarding the audio, the tr(...) in the value doesn't make sense it would need a helper function

class Audio(StrEnum):
	NO_AUDIO = auto()
	PIPEWIRE = auto()
	PULSEAUDIO = auto()

	def display_text(self) -> str:
		match self:
			case Audio.NO_AUDIO:
				return tr('No audio server')
			case Audio.PIPEWIRE:
				return 'Pipewire'
			case Audio.PULSEAUDIO:
				return 'Pulseaudio'

feel free to ignore that for now

I removed the enum translations and did some final wording changes. Should I squash the commits? Is the change to locale_generator.sh ok? Are the leftover comments in de/LC_MESSAGES/base.po ok?

Thanks for the changes
