Add integration tests for cloud Recipes (Azure, AWS)

[AaronCrawfis]

Today we test local-dev Recipes for PRs and merges as part of https://github.com/radius-project/recipes/blob/main/.github/workflows/test.yaml

We should extend our tests to include cloud Recipes, such as from AWS and Azure.

To do this we need to setup an approval pipeline similar to what we have in the radius repo, where an approval is needed by an approver/maintainer before the test can execute. This is because we need to inject cloud credentials into the test run, and we don't want that to run from untrusted contributors without a manual approval first.
