Notes:
- QuestionValidator didn't have a :name field but that seems like a mistake
- `_fields` functions can't inherit others because of some Validators
- bto/bcc fields were absent in activities, also seems like a mistake
(Well IIRC we don't or barely support bto/bcc anyway)
* Policies were put under a new module (Pleroma.Web.ActivityPub.MRF.Policy instead of Pleroma.Web.ActivityPub.MRF), but this wasn't changed in the Pleroma.Web.ActivityPub.MRF @mrf_config_descriptions
* I don't have a unit test to prevent similar problems in the future because I don't find a proper way to do it
* The descriptions in the unit tests are defined in the unit tests, so if someone changes module names in the code, the tests wont see it
* The list is generated in Pleroma.Docs.Generator.list_behaviour_implementations, but I can't do a check in the when clause of the function to see if the provided module is a behaviour or not.

* I also added for keywordpolicy as well now. It was done in the admin-fe, but is better to be done here
* I also added comments to explain why we did the _info keys (backwards compatibility)
It's easiest (and imo most proper) to use tuples {"instance, "reason"} in BE,
but for FE maps like %{"instance": "instance", "reason", "reason"} are better.
I changed it so that node_info returns maps now for simple_policy and quarantined instances.
Since mime 1.6.0:
warning: MIME.valid?/1 is deprecated. Use MIME.extensions(type) != [] instead
As for the bitstring(type) part it's because MIME.extensions only expects a string.
