stylesheets: Re-increase font-size of gl-emoji
In db703adf (emoji: Properly scale custom emoji in headings, 2023-07-07) an attempt was made to better scale custom emoji more equally with built-in emoji. During that change the font-size of was reduced. This was a mistake, and now we revert it.
While I was at it, I noticed the baseline of custom emoji is wrong, so I've fixed that.
Changelog: fixed
Closes: #419519 (closed)
