Rule Update Request: Update to existing ApiVersionPattern rule to support canonical swagger

### Lint rule description

ARM has a new initiative that will generate a canonical version of swagger from TypeSpec which amalgamate all versions of models into [a single swagger file](https://github.com/Azure/azure-rest-api-specs-pr/blob/db68ae0972e72e68bed18e657281495ebc0dfe79/specification/dinwadevtest/resource-manager/Microsoft.Contoso/canonical/openapi.json) under a new `canonical` folder which is at same level of `stable` and `preview`.

The version specified in this JSON is hard coded to `canonical`. The combination of `canonical` folder and API version being `canonical` should bypass this check.
