Need to skip the upgrade test as while running the Upgrade test it switches to main branch where prefix length is more than 16 in every case.

@iamar7 can we check upgrade test with prefix as null?
As this change is only in examples and test, then no release is required.

@iamar7 can we check upgrade test with prefix as null? As this change is only in examples and test, then no release is required.

I have tested locally with prefix as null it is working fine. In the test, I have reduced the length so that it doesn't fail in the pipeline. Also, I have updated the PR template to no release.
