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.
This enables us to have different queries for
terraform and general hcl. It solve the situation
where other dialects of hcl (nomad, packer, etc)
might use a terraform keyword and get highlighted
out of place.
