[stable/mongodb] fix failing liveness probe during long running mongodb recovery (#17502)

* fix failing liveness probe during long running mongodb recovery

this fix lets the livenes probe succeed during a long running recovery.
The new liveness probe looks for the running mongod process inside the
container, which allows a successful request. The pod will still only be
ready once the recovery is finished and only then traffic will be served
to this pod.

bumped chart version
