Improve emoji and mention matching (#24255)
Prioritize matches that start with the given text, then matches that contain the given text. I wanted to add a heart emoji on a pull request comment so I started writing `:`, `h`, `e`, `a`, `r` (at this point I still couldn't find the heart), `t`... The heart was not on the list, that's weird - it feels like I made a typo or a mistake. This fixes that. This also feels more like GitHub's emoji auto-complete. # Before ![image](https://user-images.githubusercontent.com/20454870/233630750-bd0a1b76-33d0-41d4-9218-a37b670c42b0.png) # After ![image](https://user-images.githubusercontent.com/20454870/233775128-05e67fc1-e092-4025-b6f7-1fd8e5f71e87.png) --------- Signed-off-by: Yarden Shoham <git@yardenshoham.com> Co-authored-by: silverwind <me@silverwind.io>
