update Gleam grammar and queries

With respect to the queries:

The locals scope for functions was not large enough, so a function's
parameter could outlive the function body. To fix it, we just widen
the scope to the `function` node.

See also gleam-lang/tree-sitter-gleam#25

With respect to the parser:

An external scanner has been added that fixes the parsing of strings.
Previously, a comment inside a string would act like a comment rather
than string contents.
