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.
