improvement!: port AshGraphql to Ash 3.0 (#123)
Step 1: update Ash

Step 2: mass rename Api to Domain

Step 3: Ash.Query.expr -> Ash.Expr.expr

Also change ref interpolation

Step 4: remove all warnings

Step 5: remove registries from tests

Step 6: fix filter

Step 7: private? -> !public?

Step 8: Ash.Calculation -> Ash.Resource.Calculation

Step 9: use depend_on_resources/1 -> resources/1

Step 10: add Domain to all resources

Step 11: use Ash module for all actions

Step 12: add public? true all around

Step 13: remove verbose? from options passed during Domain calls

Step 14: add simple_sat

Step 15: Ash.ErrorKind is no more, so remove code from errors

Step 16: sprinkle default_accept :* around tests

Step 17: replace Ash.Changeset.new/2 with Ash.Changeset.for_*

Step 18: calculation fixups

- Context is now a struct and arguments go under the arguments key
- Function based calculations receive a list of records
- Add a select to query-based loads
- select -> load

Step 19: pass the correct name to pass the policy in tests

Step 20: Ash.Query.new/2 is no more

Step 21: add AshGraphql.Resource.embedded? utility function

Use that instead of Ash.Type.embedded_type?(resource_or_type) since resources
are not types anymore

Step 22: handle struct + instance_of: Resource in unions

Resources are not type anymore so they need to be passed this way in unions

Step 23: ensure we only check GraphQL actions for pagination

All reads are now paginated by default, so this triggered a compilation error

Step 24: swap arguments for sort on calculations

Step 25: remove unused debug? option
