If I am reading comments ([example](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/38304#note_388944139)) and want to quickly see what's in the patch, currently I have to download it and open in text editor, and later delete the file. ### Proposal Add a Preview button next to links to .patch files. On click, download file contents and display in a code block with diff syntax highlighting
