Allow new file and edit file preview if it has editable extension (#23624)
Close #23579 Inspired by [idea](https://github.com/go-gitea/gitea/issues/23579#issuecomment-1475429247) from @brechtvl In this PR, the behavior is when extension switches from writatble to not, preview will hide, and vice versa. demo: https://user-images.githubusercontent.com/17645053/226786119-d20063da-8763-41ce-9b00-ae34929120e1.mov --------- Co-authored-by: silverwind <me@silverwind.io>
