Co-authored-by: ObserverOfTime <chronobserver@disroot.org>

* removed priority from (dot_expression left: @none) capture, since it's
at the end of the file anyways

* removed comments listing unused captures

* reverted @error capture in nim_format_string/highlights.scm back to
@none

* condensed string alternatives in injections.scm

Co-authored-by: ObserverOfTime <chronobserver@disroot.org>

* condensed string alternatives in injections.scm (second part)

Co-authored-by: ObserverOfTime <chronobserver@disroot.org>

* added comment to explain reasoning behind priority use

* swapped order of @punctuation.delimiter and @operator to get rid of
superfluous comment

* moved macro and template keywords to @preproc capture

* removed priorities in highlights.scm and shifted @parameter capture
behind @type capture

* improved formatting in locals.scm

* added queries for missing cases of @definition.namespace capture in
locals.scm

* removed some trailing whitespace

* added @namespace queries for highlights.scm

* bumped parser version again

* removed superfluous @type capture

* removed `@type`s `has-ancestor` and removed `(_ (_ ...` structures,
but added priorities

* added missing @constant capture to some queries in highlights.scm

* fixed priority numbers so they work when injecting nim (in markdown)

* added @none captures back to injection targets

* added (assembly_statement) injection query

* added indent queries

* removed indents.scm again

* added some missing queries for dot_generic_call, concept_declaration and
pragma_statement
