Ctrl-e keybind does not work #70

Fixed by https://tangled.org/jonmsterling.com/ocaml-forester/commit/159c8484463dbda95e69813285266c0b4c51dd14

This was because window.sourcePath was not properly set. It now works by emulating a click on the edit button, which avoids some code duplication and also keeps in sync with HTMX swaps. (I don't remember if sourcePath was properly updated on swaps)
