feat(fmt): stabilize CSS, HTML and YAML formatters (#25753)

This commits stabilizes CSS, HTML and YAML formatters
in `deno fmt`.

It is no longer required to use either of these flags:
- `--unstable-css`
- `--unstable-html`
- `--unstable-yaml`
Or these `unstable` options in the config file:
- `fmt-css`
- `fmt-html`
- `html-yaml`
