Fix probes for pgadmin (#13820)

**Description**
The probes created a session file in the sessions folder every probe, so
multiple files per minute. Over the course of a few months, it great to
a few gigabytes for my install. Changing the probes to /misc/ping is the
solution for kubernetes, as I read in a pgadmin github issue.

I changed runAsNonRoot to true, I don't know why it was set to false.

I also changed the defaults in questions.yaml to correspond to the
placeholders in values.yaml.
