refactor(content-releases): remove permission checks and update endpo…

[markkaylor]

What does it do?

Release Action

• Removes the permission checks on entry and filtering of entries that don't pass the permission check
• Reshapes the populated entry to use a meta entry meta data (content type display name, locale)

//...release action stuff...//
"entry": {
    "contentType": {
        "mainFieldValue": "name",
        "displayName": "Restaurant"
    },
    "locale": {
        "name": "English (en)",
        "code": "en"
    }
}

Release findOne

• Forward the query from the controller to the service so the pagination works
• Update the findOne service to populate and sanitize creator fields

// ... release stuff ... //
"createdBy": {
  "id": 1,
  "firstname": "George",
  "lastname": "Harrison",
  "username": "Thebestbeatle",
},

Why is it needed?

• We decided for now to not check permissions on every single entry. We may re-introduce granular permission checks in the future.
• Gives the frontend all the data it needs for the Release page

How to test it?

• Make a request for a single release: http://localhost:1337/content-releases/:id
• Check the data looks correct
• Make a request for a release's actions: http://localhost:1337/content-releases/3/actions?page=1&pageSize=20
• Check it is returning only the actions for the requested release, the pagination works, and the entry meta is as described above where applicable.

Tested locally and it's working great. There is one small lint error to fix
