[typescript-react-query] add ability to customize react-query key with a directive

**Is your feature request related to a problem? Please describe.**

The react-query key is automatically generated from the query name, but there are situations where you might want to change the query key (e.g. for easier invalidation).

**Describe the solution you'd like**

Add a `@reactQueryKey` directive on `QUERY` to allow customizing the generated key.

**Describe alternatives you've considered**

Add an argument to the generated hook that allows specifying the key. This might be useful but also feels like it could be overkill.
