resolveFully not implemented

[alinemombach-amadeus]

Problem:
The project includes a function to set the resolveFully, which is intended to resolve internal references. However, it appears that the ResolverFully class is not implemented within the project, therefore internal references remain unresolved.

Expected Behavior:
When resolveFully is set to true, the system should utilize the ResolverFully class to resolve internal references as intended.

Steps to reproduce:

options.setResolve(true);
options.setResolveFully(true);
AsyncParseResult parseResult = asyncAPIV2Parser.readContents(myString);
AsyncAPI asyncAPI = parseResult.getAsyncAPI();

Input asyncAPI spec:

asyncapi: 2.0.0
info:
  title: Not 2.0 example
  version: 1.0.0
channels:
  test:
    subscribe:
      message:
        $ref: '#/components/messages/testMessage'
components:
  messages:
    testMessage:
      payload:
        type: string

will result:
