AshGraphql 0.28.1 breaks when resource is in more than one API

[sezaru]

Describe the bug This bug is for a project that I haven't update to Ash 3 yet, so I'm not sure if the same bug is reproducible in Ash 3 with the latest version of Ash Graphql.

Adding a resource that is used by AshGraphql in two or more APIs, will break compilation.

To Reproduce Have a resource that has AshGraphql.Resource extension, then add it to two different APIs which also uses AshGraphql.Api extension.

During compilation, it will fail with a bunch of errors like this one:

== Compilation error in file lib/core/graphql/schema.ex ==
** (Absinthe.Schema.Error) Compilation failed:

Expected behavior I think that AshGraphql should identify that the resource is the same and work with multiple APIs

** Runtime

• Elixir version 1.16.3
• Erlang version 26.2.5
• OS Fedora Silverblue 40
• Ash version 2.20.3

AFAIK this is fixed in 3.0. Do you need a back port fix or can you wait to update to 3.0 for the fix?

We do plan to upgrade to Ash 3 in the next few weeks, so for now we can just "duplicate" the resource in the other API as a workaround. Thanks!
