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 ...)

update: #17902 did add support in terms of api 🎉

Did you mean to support suggestion as a diff and with buttons to apply the patches?

[6543]

suggestion support as per github, would be nice but is likely harder to implement.

a diff is easier to implement for the start as you can use the described api

example:

diff --git a/templates/admin/auth/list.tmpl b/templates/admin/auth/list.tmpl
index b4a703e41..64db93a3e 100644
--- a/templates/admin/auth/list.tmpl
+++ b/templates/admin/auth/list.tmpl

                        </div>
                </h4>
                <div class="ui attached table segment">
-                       <table class="ui very basic striped table unstackable">
+                       <table class="ui two basic striped table unstackable">
                                <thead>
                                        <tr>
                                                <th>ID</th>

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

For apply a patch, isn't it implemented in #17902? We just add a form in UI but not upload a file to do that?

@6543 for suggestions, there is #14765 - this seems to be only about raw diffs.

It would be nice if this also applied to .patch attachments.
