What problem is this solving for you? I find this feature quite useful, at least for highlighting SQL, and I've used this with graphql in the past. And, slightly cursed, but also for highlighting bash and python using JS as the glue code.

Edit: nevermind, somehow I glossed over the issue.

Happy to add those to the list! sql, python, and bash... any others?

slightly off-context (as this PR currently only limits injection and not extend it), but is it possible to support Bun's $ shell API?
the syntax looks similar to bash.

https://bun.sh/docs/runtime/shell

Yeah that would look like:

; Parse the contents of $ template literals for shell commands

(call_expression
  function: [
    (identifier) @_template_function_name
    (member_expression
      property: (property_identifier) @_template_function_name)
  ]
  arguments: (template_string) @injection.content
 (#eq? @_template_function_name "$")
 (#set! injection.language "bash"))

And would also work for https://github.com/sindresorhus/execa and https://github.com/google/zx. I can make a PR after this one for that feature.
