Version 2.2.1 of the grammar adds extended support for HLL (C, C++,..)
expressions. Quite a few node types were added, renamed or removed in
the process.
This change brings the highlight queries in sync with the ones found in
the repository of the grammar. The highlighting tests "look" okay after
updating the queries.
Recently, Codeberg had some reliability issues. That is why the language
is now using the mirror repository on GitLab as source instead.
