Increasing MariaDB startupProbe timeout

Browse Source 
In the event of an uncontrolled reboot on a Standard configuration,
we were seeing a behavior where the MariaDB pods kept trying to elect a
leader and restarting until the pods get to CrashLoopBackoff. After
checking the logs closely and reproducing the problem quite easily by
deleting both pods at the same time, we came to the conclusion that the
cluster wasn't having enough time to elect a new leader and recover from
the crash. This patch increases the timeout for the startup probe of the
mariadb statefulset with some slack to allow databases that are in
production to fully resync the data between the 2 pods.

Closes-Bug: #1938346
