Add Button to apply diff comments to PRs

[6543]

if you leaf a code-block commit with: ```diff ...

show a button to commit the diff to the PR
like suggestions in PR review comments but more powerful

for those who are interesting to implement it:

• beware non-utf8 encodings!
• backend was added via Add apply-patch, basic revert and cherry-pick functionality #17902

It would have to either be a git formatted diff or even better patch, or else be attached to a file somehow.

@guillep2k you could link this issue to #8659 (just noticed ...)

☝️ suggestion support would be also nice, but you have to create a diff/patch form the infos first ... (what was original there ...
