Build/Test Tools: Fix the precommit:emoji script.

GitHub recently sunset support for Subversion, causing the `precommit:emoji` Grunt script to break. Since there’s no direct replacement for `svn ls` in Git, this has been replaced with a query through the GitHub CLI.

This also adds a step in the workflow that tests the build process to run the `precommit:emoji` script to ensure no changes to built files are missed when updating the Twemoji library in the future.

Follow up to [57626].

Props kraftbj, peterwilsoncc, swissspidy.
Fixes #60520. See #57600.
