docs(luacats): support backtick captured generic type
Problem:
While LuaCATS's generics system are still considered WIP by luals, they
currently support type captured generics.
See "Capture with Backtick" example:
https://luals.github.io/wiki/annotations/#generic
Solution:
Add support for it in the LuaCATS grammar
