Improve testing speed by skipping it for certain PRs

[derberg]

We have https://github.com/asyncapi/generator/blob/master/.github/workflows/pr-testing-with-test-project.yml that is really long running.

And it runs sometimes when it is not needed, when there are PRs from bots doing some simple changes, sometimes readme only.

Add to the workflow if statement that we already have in https://github.com/asyncapi/generator/blob/master/.github/workflows/if-nodejs-pr-testing.yml#L21
