chore: Restore add_auth_token(s) as deprecated for backward compatibility

This PR addresses a breaking change introduced by the removal of `add_auth_token(s)` methods in #182. To ensure backward compatibility and facilitate a smoother upgrade path, these methods are now reintroduced but explicitly marked as **deprecated**. Users are encouraged to migrate to the new `add_auth_token_getter(s)` methods instead.

> [!NOTE]
> The `strict` flag in the deprecated methods are not used anymore since the functionality of the `strict` flag has been changed (see #205 for more details).
