This commit replaces the out-of-date builder in the flake which relied on submodules for fetching and the compiler for building. Now we disable fetching and building explicitly with the environment variable and then use builtins.fetchGit and a derivation mostly derived from upstream to compile the grammars. Anecdotally, this is still quite slow as builtins.fetchGit does not seem to do shallow clones. I'm not sure I see a way around it though without recording sha256s, which seems cumbersome.
