When there's a PR for a translation, apart from adding the `lang-all` label, also add a label for the language.

There will be a label for each language using the language code, like `lang-{lang code}`, for example, `lang-es` for Spanish, `lang-fr` for French, etc.

* Add the specific language label.
* Add the label `awaiting-review`.
