[AndyScherzinger]

• Resolves: noid

Summary

• first batch of files with SPDX headers added
• ensured all names are wihtin the authors' file
• renamed some files to markdown (authors and copying-readme) for better formatting
• added a dep5 file with definitions for all translations.

This PR brings us to

• files with copyright information: 8295 / 10990
• files with license information: 4243 / 10990

TODO

• review
• create further PRs after each SPDX PR got merged, to get to 100% in batches - in the end for every file in the repo there will be a copyright and license info present.

Keep in mind the the next upgrade will always work with the already shipped updater!

@AndyScherzinger during release building, we delete COPYING-README from bundled apps. Should this stay?

No, can still be removed.

I'll create a PR, will need a review since I can't say if expected files which are missing would be an issue.

I reverted the renaming of the root folder files, to keep the changeset for the updater small(er) #45250
