test(ingress): align assertions with the release name and namespace

The suite header was changed to the release `gitea-unittests` in the namespace `testing`, but the assertions still
expected the previous `gitea-unittest` and `gitea-debug`. That made four cases fail on the rendered resource name, the
`app.kubernetes.io/instance` label and the backend Service name.

Renovate comments had additionally been copied into the expected `app.kubernetes.io/version` and `version` label values.
They only matched by accident, because YAML strips the trailing comment from an unquoted scalar. Removing them keeps the
assertions honest about what is actually compared.
