p4: skip integration tests for now

Created by: jhchabran

@mollylogue it seems that while your PR in https://github.com/sourcegraph/infrastructure/pull/3699 correctly made the CI to run those integrations tests, they have the side effect of also blocking the main branch as they're failing.

By adding just a skip statement, you can keep working on this as the agents will have the env vars, but the main branch will be unblocked.

Test plan

Should not run that particular tests. CI.
