feat: assign users to teams via OIDC claims (#1393)

This change adds the ability to sync teams via a custom openid claim. Vikunja will automatically create and delete teams as necessary, it will also add and remove users when they log in. These teams are fully managed by Vikunja and cannot be updated by a user.
