fix: use schemas only from request body

[vitormattos]

Scope

Have schemas that only exists at requestBody and at this case, if we don't fetch from body will throw an error "Can't resolve $ref" when run openapi-typescript build.

How to reproduce

• Create a new endpoint with an object as param

  /**
   * Route with param
   *
   * @param FakeParam $fake Fake param
   * @return DataResponse<Http::STATUS_OK, array<empty>, array{}>
   *
   * 200: Personal settings updated
   */
  #[OpenAPI]
  public function fakeMethod DataResponse {
      return new DataResponse();
  }

• Add the FakeParam to ResponseDefinitions

   * @psalm-type NotificationsRequestProperty = array{
   *     publicKey: string,
   *     signature: string,
   * }

• Build with the follow command:

  npx openapi-typescript -t

Expected behavior

> dummyapp@0.0.1 typescript:generate
> npx openapi-typescript -t

🚀 openapi@v1 → ./src/types/openapi/openapi.ts [141.7ms]

Actual behavior

> dummyapp@0.0.1 typescript:generate
> npx openapi-typescript -t

 ✘  Can't resolve $ref

                throw new Error(problem.message);

Tests

Considering that the test only build the json files and not the ts files, I didn't implemented tests.

Can I go ahead and implement a test to check if openapi-typescript will build without problems?

Preferably the logic is not duplicated with the code above, since it is exactly the same and only operates on a different part of the spec.

Could you comment more about this?

Yes that would be nice, I thought about extending our current checks against existing repos by running openapi-typescript inside them if they use it. That should at least prevent regressions.

The logic is the same as a few lines above but complex enough that it should not be implemented twice.

What you think about put this in a separated PR to don't mix with the context of this PR? I understand that tests are very important but would be best separate the scope to merge this fix more quickly.

Did you have any suggestion to this? This file isn't object oriented, is a point that make the reuse of code a bit complex. To prevent a duplication of code, maybe the both loop could be moved to Helper class.

Yes, but a simple test for this fix still needs to be added to this fix.

Can be done easily by putting all elements into a single array and then looping over them instead of looping over them separately.
