da6fb315 - Cleanup non-generic assertions in our deploy test suite (#90894)

Cleanup non-generic assertions in our deploy test suite (#90894) This makes sure we don't have assertions that will only pass in one environment e.g. these should work for running against bun and not just node or against a local metadata URL not just a deployed https fully qualified domain. Ensures others can leverage this test suite for their own verification easily.
