Skip test_url for AI containers

[rewenila]

Skip tests/test_metadata.py::test_url for AI containers. This test fails for the vLLM containers (vllm-openai, lmcache-vllm-openai, lmcache-lmstack-router), as the application URL doesn't match the container name:

FAILED tests/test_metadata.py::test_url[container89-lmcache-lmstack-router-application] - AssertionError: expected LABEL com.suse.application.lmcache-lmstack-router.url = ('https://apps.rancher.io/applications/lmcache-lmstack-router', 'https://apps.rancher.io/applications/lmcache-lmstack') but is https://apps.rancher.io/applications/vllm
assert 'https://apps.rancher.io/applications/vllm' in ('https://apps.rancher.io/applications/lmcache-lmstack-router', 'https://apps.rancher.io/applications/lmcache-lmstack')

@rewenila rather than reducing test coverage, would it be possible to fix the definition in

BCI-tests/tests/test_metadata.py

Line 335 in e60fa36

"lmcache-lmstack-router",

instead or is there any downside of that I don't see?

I thought the definition there should match the name in the image label. Won't other tests fail if I change it? Maybe I'm missing something.

I could also skip the url test for the vLLM containers only, instead of for all the AI containers.
