Custom Query with [String] return type generates String return type instead.

[thekevinbrown]

Describe the bug
When defining a custom query, if you define the getType value as () => [String] the custom query ends up with a String return type in the schema.

To Reproduce

graphweaverMetadata.addQuery({
	name: 'test',
	getType: () => [String],
	resolver: () => ['a', 'b'],
});

Expected behavior
Expected to be able to query { test } and get back ["a", "b"] in the result.

Actual behavior
test is correctly created in the schema, but the return type is generated as String instead of String[].
