Fix `make fmt` and `make fmt-check` (#18633)

* Run 'make fmt'

'make fmt' currently produces this change, I'm not sure how CI did not
fail on it, I made sure I have `mvdan.cc/gofumpt@latest`.

* Fix 'make fmt-check'

`make fmt-check` did not run all commands that `make fmt` did, resulting
in missed diffs. Fix that by just depending on the `fmt` target.

Includes: https://github.com/go-gitea/gitea/pull/18633

* Make gitea-fmt work with -l and -d and integrate gofumpt

This implements -l, -w and -d with gitea-fmt and merges gofumpt.

* Apply suggestions from code review

* use -l instead of -d for fmt-check
