bug#55522: Display of color emoji on macOS

[Tor Kringeland]

Currently the default Apple Color Emoji font works with Emacs on macOS and 
gives color emoji. However, when I try to use the open font "twemoji", Emacs 
displays the black-and-white version of it. The configuration I'm using is the 
following

  (set-fontset-font t 'emoji "Twitter Color Emoji")

Is this something that should work with Emacs and is a bug, or is it something 
for which there is no support yet? [2] mentions something about the font only 
working on Firefox (and not Chrome or Safari, e.g.). I'm using a nightly build 
of Emacs 29 on macOS 15.5.5.
