syntax: Don't force lower-case for filenames (helix-editor#4346)

Just like for grammars we currently force a lower-case of the name for
some actions (like filesystem lookup). To make this consistent and less
surprising for users, we remove this lower-casing here.

Note: it is still the preferred way to name both language and grammar in
lower-case
