CI: Purge beta builds on new release

[aawsome]

An ever-growing repo of beta builds increases the execution time of the CI a lot.

Idea: on release, do

rm -rf .git
git init
git remote add origin git@github.com:...
git add *
git commit -am 'new release'
git push -f origin master

What about moving beta builds to a website like beta.restic.net? I would be willing to sponsor domain and hosting.

Other possibility:

git checkout --orphan freshBranch
git add -A
git commit
git branch -D main 
git branch -m main 
git push -f origin main
git gc --aggressive --prune=all
git push -f origin main

We should move the files to some other space at one point, for sure. Also, because we don't need any history of nightly builds, really. For now, I would say it's sufficient, though, as we don't have more stress with administrating that webspace. So we can always do that at a later date. Thank you for the proposal!
