Better error for typos in Aggregates when using AshGraphQL

[BryanJBryce]

Is your feature request related to a problem? Please describe.
The AshGraphQL library gives an unhelpful error when there is a typo in an Aggregate definition where if AshGraphQL is not used Spark gives a helpful error.

Describe the solution you'd like
Somehow the Spark error should be surfaced or the AshGraphQL error should give as good of information as the Spark error

Additional context
I've created an example repo which has a simple project with two branches which contain the typo error with the only difference being that one branch has AshGraphQL installed and the other does not.

https://github.com/BryceLabs/ash_issues_examples/tree/aggregate-typo-issue
https://github.com/BryceLabs/ash_issues_examples/tree/aggregate-typo-issue-graphql

In the project there is an Order resource which has_many OrderItem resources. Order aggregates the subtotal calculation of OrderItem via a sum. However, there is a typo:

aggregates do sum :subtotal, :order_items, :sub_total end

sub_total should be subtotal

The error given by the plain Ash project is this:

** (EXIT from #PID<0.98.0>) an exception was raised:
** (Spark.Error.DslError) [App.Store.Order]
aggregates -> sub_total:
All aggregates fields must be attributes or calculations. Got: :sub_total
