[System tests] Skip chart patching in provctl patch

[Hedingber]

Our CI that builds image tag the images with <latest-version>-<commit-hash>
the <latest-version> is resolved by curl -sf https://pypi.org/pypi/mlrun/json | jq -r '.info.version' which (as of writing this) outputs 0.5.4.
It means that currently our system tests running on development are patching the system to versions like 0.5.4-daafbed the problem with this is that since this 0.5.x it makes provctl patch picking 0.4.x chart, while this PR that will be only in 0.6.x requires this chart PR that will only in 0.5.x charts.
Bottomline provctl patch gives the wrong chart which is causing these failures in the TestJobs suite:
