[auto-detect] Add support for smart grouping of CWV recommendations

Use Case

As a marketer, I want to have my CWV suggestions grouped for pages of similar type and/or template.

Technical

On EDS, we should automatically group pages by explicit templates metadata. For other AEM versions, we should look at the presence of template metadata as well, or the presence of a clientlibs with the "template" string.
We can fall back to manual grouping as a last resort.

Please ensure your pull request adheres to the following guidelines:

• make sure to link the related issues in this description. Or if there's no issue created, make sure you
  describe here the problem you're solving.
• when merging / squashing, make sure the fixed issue references are visible in the commits, for easy compilation of release notes

If the PR is changing the API specification:

• make sure you add a "Not implemented yet" note the endpoint description, if the implementation is not ready
  yet. Ideally, return a 501 status code with a message explaining the feature is not implemented yet.
• make sure you add at least one example of the request and response.

If the PR is changing the API implementation or an entity exposed through the API:

• make sure you update the API specification and the examples to reflect the changes.

If the PR is introducing a new audit type:

• make sure you update the API specification with the type, schema of the audit result and an example
