fix: Fixed flaky fork template test case (#36200)

## Description
Root Cause Analysis (RCA):
The issue stemmed from the use of hardcoded templates in our tests,
which introduced inherent flakiness. This approach caused intermittent
failures, particularly when the hardcoded template was not available or
had changed.

Solution:
I have resolved this by implementing dynamic locators that select the
first available template during the test execution. This ensures greater
stability and reduces flakiness. The only scenario where this approach
could fail is if no templates are available, which would be a
product-level blocker rather than a test issue.


Fixes #`36199`
