ci: Get api.json from Misskeyでupload-artifact@v4で同名artifactでエラーになるのを修正 (#12770)

* ci: upload-artifact@v4で同名artifactでエラーになるのを修正

Co-authored-by: おさむのひと <46447427+samunohito@users.noreply.github.com>

* report-api-diff.ymlの最中にエラーが発生したときに分かりづらいので、PRにコメントを残すようにする

* 古いget-api-diffを使ってるactionとの互換性をもたせる
