German translation of the README.md

[Firq-ow]

Status:

• Translated README.md to German (new file: README.de.md)
• Links in README.de.md are all working to my knowledge
• Proofreading by another person would be highly appreciated
• A reference from README.md is not yet included
• Maybe check if any of the german chars break anything (ä, ö, ü, ß)

On that note:
My german example with scrcpy --window-title "Mein Gerät" results in an awkward title (see image below)

This isn't a mayor issue, as scrcpy continues to work normally without errors.

Also, thank you all for providing this awesome application. Keep it up :)

Thank you 👍

I added a commit (that I will squash before merging) to:

• fix some spacing issues
• reference the Windows release from the main README (so that it always points to the latest version)
• removed the "translations" section from README.de.md (we can't keep up to date the translations versions/links from all translations)
• added the link to the German translation from the main README

Branch: pr3023

Could you review it, please? Is it ok to you?
