feat: Add Support with Typed Response from /api/access

[matthijs166]

At the moment, I do my own fetch to /api/access and import the Sanitized Permissions type from the backend folder.
It isn't correctly typed, the collections and fields from the config are not recognized.

Would be awesome if it is included in this client.
