Run CI/CD tests using cargo #14
Description
Rather than maintain tests across different grammars, write tests for the staging environment for use with cargo and run either in the deploy or a new, dependent test job against the staging environment.
To prevent breaking normal cargo test workflows, perhaps these tests can either condition on some environment variable being defined e.g., AZURE_FUNCTIONAPP_URL (early termination, hence misleading test results normally) or a feature or config that the test environment could enable.
