MDL-72791 behat: Unrelated, add the @skip_interim tag

This commit is UNRELATED to the MDL-72791, but we need the
@skip_interim tag added to one scenario that is causing lots
of noise and failures @ CI infrastructure.

So we are using MDL-72791 (this extra commit) to add that tag ASAP.
(sorry for the noise, the tag will be removed once the scenario
or its causes are fixed).
