Subject: [PATCH] Use `@tag.doctype` for HTML doctype highlights (#18024)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR updates the following extensions to use the `@tag.doctype`
selector for highlighting HTML doctypes:

- Astro
- Elixir (HEEx)
- HTML

Additionally, it also changes the base selector for HTML tags from
`@keyword` to `@tag`.
