feat: add API descriptor with API_SPECTRAL with AsyncAPI/OpenAPI support

Add API descriptor as modified copy of the OPENAPI descriptor.
Deprecate the contained linter OPENAPI_SPECTRAL.

Add `.spectral.yaml` as default config file to `TEMPLATE/`
as modified copy of `.openapirc.yml` with rulesets for
AsyncAPI and OpenAPI (previously, only OpenAPI).

Closes: oxsecurity#3387
