[ST] Fix FIPS check in case that ConfigMap is missing

[im-konge]

Type of change

• Test fix

Description

This small PR fixes the check if the cluster where we are running our STs is FIPS - in case that the ConfigMap is missing, the check will throw NPE.
The fix should ensure that the false is returned in case that the ConfigMap is missing, otherwise the data are taking from CM.

Checklist

• Make sure all tests pass
