Fixes [#34027](https://github.com/go-gitea/gitea/issues/34027) Discord does not allow for description bigger than 2048 bytes. If the description is bigger than that it will throw 400 and the event won't appear in discord. To fix that, in the createPayload method we now slice the description to ensure it doesn’t exceed the limit. --------- Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> (cherry picked from commit 013b2686fe6d306c4fb800147207b099866683b9)
