SNS section not compatible with AsyncAPI 3.0.0

SNS README is not compatible with AsyncAPI 3.0.0
E.g. the section mentions subscribe which is not supported anymore

SQS README has the same issue.
Any news on that?

@jturek-olx @derberg Thanks for pinging me. I'll talk to @dpwdec

@jturek-olx @derberg I'll draft a new version that uses AsyncAPI V3. However, as we know that V2 is stilled being used widely I think we should keep the V2 bindings available on master. So should we disambiguate them in same way the main project does with a 2.x.x folder and a 3.0.0 folder?

I've raised a PR for SNS: https://github.com/asyncapi/bindings/pull/260/files
