As discussed in PR#5421, capturing `@error` is inconsistent, requiring
deep nesting (or priority) in order to correctly have red backgrounds to
it.
Some queries has this capture, some don't. For consistency purposes,
removing all of them is more preferable.
For re-enabling error, either add `(ERROR) @error` or `(ERROR _ @error)`
to your custom queries.
- The directive type does not longer includes `::`.
- The content of the directives is not longer interpreted as rst,
but it uses language injection for it.
- Fix a query to allow to capture targets without link.
- Reset the content of the math role so it can be highlighted by the
injection instead.
Problems I found:
- Capturing the same node with @language and @content will raise an
error.

Harcoding the language works, Using the offset predicate doesn't work
either `(#offset! 0 0 1 0)` nor `(#offset! 0 0 0 5)`
- Generating the grammar using `tree-sitter-cli@0.17.x` breaks
nvim-treesitter, `@0.16.9` works.
