Operator E2E test sporadically failing due to the timing issue

[lokeshrangineni]

Operator E2E test sporadically failing due to the timing issue based on the availability of the pods status. We have to expect reliable execution on every PR to avoid the inconsistency.

For Example:

https://github.com/feast-dev/feast/actions/runs/12896520988/job/35959688148?pr=4930

Here is the error we are seeing.
