10986: fix: Fix lint completions not working for unclosed attributes r=Veykril a=Veykril

Fixes #10682
Uses keywords and nested `TokenTree`s as a heuristic to figure out when to stop parsing in case the attribute is unclosed which should work pretty well as attributes are usually followed by either of those.
