After a chaotic change of ownership, the `twitter/twemoji` library is now considered abandoned. After waiting for this moment to arise, a fork was created by several former employees who had maintained the library which lives at `jdecked/twemoji` on GitHub. This switches out where the underlying source code comes from for the library, and applies the 15.0.3 update, which adheres to the Unicode 15 spec and adds support for all Emoji introduced in Emoji 15.0. This does not update the underlying `precommit:emoji` Grunt script responsible for updating `formatting.php`. After GitHub recently sunset support for SVN, the current process needs to be replaced with a new one. This will be handled in #60520. Let the masses rejoice for the 🐦⬛ singing in the dead of night, secure 🛜, aromatic 🫚, and some very silly 🪿🪿. RIP Twemoji. Long live Twemoji! Props peterwilsoncc, kraftbj, jeffpaul, azaozz, dd32, hareesh-pillai, jorbin. Fixes #57600.
