oneOf rule should apply to OpenAPI 2.0 only

[arthurcogo]

The ruleset currently has the following rule:

However, the AWS documentation states:

oneOf is not supported for OpenAPI 2.0 or SDK generation.

I have been able to use oneOf successfully in API Gateway with 3.0 which seems to confirm this.

Therefore, I suggest that this rule only applies to OpenAPI 2.0 specs.

Thanks for the feedback, unfortunately due to time constraints I'd not worked out how to differentiate between the two AWS OpenAPI implementations, so am assuming that this library should only work with the v3 fork of OpenAPI.

As the AWS documentation has been updated, I will fix this by removing the warning around oneOf not being supported, and make it clearer in the README that this is only targetting openapiV3-aws.

Thank you so much - this has now been released.
