Fix broken code editor diff preview (#23307) (#23320)
Backport #23307

Close #23265, the code editor diff preview has been broken for long
time.

* Fix the regression for `data-line-num`
    * `.code-diff` is necessary to show the line number
* Fix the regression for #12434
* The diff:
[12434](https://github.com/go-gitea/gitea/pull/12434/files?diff=unified&w=1)
    * It hides the Type(4) (aka HunkHeader)  for unexpected cases.


Diff with ignoring whitespaces:
https://github.com/go-gitea/gitea/pull/23307/files?diff=unified&w=1

Before: see the issue #23265
