[ResponseOps][Rules][Meta] Add OAS support for Rules APIs

[cnasikas]

The Core team added support for OAS in the Kibana routes. To provide users with an up-to-date OAS for the documented public Rules API we need to a) version the remaining HTTP routes b) move the parameters schema of all rule types in a package and c) register the OAS schema on each route. Below, for each category, all steps to achieve our goal are listed.

I added the GET /api/alerting/_health endpoint to the tasks.

[jcger]

I miss the tasks to update params param to use the definition created in the new package

[cnasikas]

Good point @jcger! I will update the issue accordingly.
