Michael Davis cdd6c8d91e Update Erlang highlights
* Macros that start with underscore were incorrectly marked as
  'comment.unused' rather than 'keyword.directive' due to an ordering
  issue of those two patterns.
* Recognize escripts as Erlang by the shebang.

Michael Davis 5a1bed2b70 Add parameter highlights to Erlang
This doesn't work robustly (within pattern matches). Only regular
bindings are highlighted as parameters. In order to highlight all
parameters even in matches, we would need an arbitrary nesting operator
in queries which doesn't exist yet in tree-sitter.

Michael Davis 452f7d071c Improve Edoc highlighting within Erlang
This highlights edoc within Erlang comments. The trick was to have
the Erlang grammar consume newlines and then give them to EDoc in the
injection to use so that line-wise elements could be parsed accurately.

Michael Davis ac669ade05 erlang: Fix highlighting of empty records
For example

    -record(state, {})

Would not highlight `state` as a type since the alternation didn't
allow for an empty tuple. Allowing the inner atom of the tuple to be
optional fixes this case.

Michael Davis 19acbfe02d erlang: highlight records with macro names
You might use a macro like `?MODULE` to name a record:

    -record(?MODULE, {a, b, c}).

With this fix, the record fields correctly get `variable.other.member`
highlights.

Michael Davis e4e8a39bf7 replace module captures with namespace
`module` is undocumented and does not exist in other themes. The
equivalent existing scope based on usage (Elixir for example) is
`namespace`.

Michael Davis bd527c84e6 erlang: highlight unary '#' as punctuation.bracket
The '#' character may either be interpreted as a map when used
like so:

    %% Example 1
    #{a => b}

Or as an operator which updates an existing map when the left-hand
side is an expression:

    %% Example 2
    MyMap#{a => b}

This commit changes the highlight to `punctuation.bracket` when used
as a character in a literal map (example 1) and keeps the `operator`
highlight when used for updating (example 2).

Michael Davis 82da9bd4f2 update Erlang grammar and queries
The update to the grammar itself covers the case where the document
is a single expression without a trailing newline such as "min(A, B)".
A small change to the parser now parses these expressions correctly
which improves the display of the function head in the signature
help popup.

The update to the queries marks 'andalso', 'orelse', 'not', etc. as
`@keyword.operator` which improves the look - it looks odd to see
operators that are words highlighted the same as tokens like '->'
or '=:='.
