chore(i18n): update German translation

[trueberryless]

🧭 Context

i18n

📚 Description

This PR updates the German translation.
It also changes the headings of each page to follow the recognizable "lowercase" format, as in German you would normally start many of the words with a capital letter, but I like the look, so I thought it would be nice to translate it into German as well 🥇

Also I noticed that the vacation section is always getting delete when I run the comparison script. It could be that the CI will delete it again (thanks autofix), because this line removes it for some reason:

npmx.dev/scripts/compare-translations.ts

Lines 410 to 411 in 50491e6

	// TODO: removing vacations entry key for temporal recharging page
	delete referenceContent.vacations

If this is actually some leftover, I'll PR to remove those lines 👍
