Webhook wip (#6371)

This PR introduces the following changes:
- Add the ability to filter webhooks by objectSingularName and Actions
- Refactor SettingsWebhookDetails edition to not use react-hook-form
(which will be deprecated on the whole project)
- Updating the tests with a complex set of mock (we just need to fix ~30
of them now :D)
