"Unsupported type" error on `codegen` when custom type in Map

[sraver]

Describe the bug
"Unsupported type" error raises on the type generation when using custom types on a Map on the schema.graphql.
It also happens on the generation of types when importing an interface with custom types on a Map.

Please provide the steps to reproduce and if possible a minimal demo of the problem.

1. Define an interface like:

type Module {
    getMetadata: Metadata!
}

type Metadata {
    tokens: Map! @annotate(type: "Map<String!, [Token!]!>!")
}

type Token {
    address: String!
}

2. Build and deploy the interface
3. Import the interface into a module as usual, and implement type Module implements Interface_Module {}
4. Generate types yarn codegen

Expected behavior
Process should complete as usual and the types should be created inside src/wrap

Screenshots / logs

...
✅ Manifest loaded from ./src/__tests__/types/polywrap.app.yaml
🔄 Generate types
❌ Failed to generate types: Error: Unsupported type Token
Error: Unsupported type Token

Relevant environment details:

• Debian 11
• Polywrap 0.9.3

Additional context
The error doesn't happen when instead of a custom type, a primitive one is used, like String.

Some updates on the issue. In our schema-compose package, we aren't adding the namespace to the map types which causes the codegen to fail.
