Code Issues Proposed changes

Adjust timeout for coredns readinessProbe

Browse Source 
The timeout value for the readinessProbe of CoreDNS was increased. This
adjustment was necessary to avoid issues during stress testing,
ensuring that the component can properly handle high-load situations
and prevent premature failure in readiness checks.

Test Plan
=========

[PASS] Execute fresh install and verify that the readinessProbe timeout
parameter for the coredns pod has been set to 5 seconds.

Closes-Bug: 2092582
