CI: Make sure oc command is available before any oc operations

As part of crc-org#3782 debugging steps are
added to figure out why the `oc login` require insecure sometimes but
this logic fails in case the `oc` binary is not part of system path.
This PR make sure that the oc command available before those debugging
steps.

fixes: crc-org#3792
