Run tests for Providers also for Airflow 2.8

This is a follow-up on apache#39513 to add support for running Provider
tests against Airlfow 2.8 installed from PyPI.

The changes include simplifying specification of providers to exclude
for each version and adds a warning for a problem detected in common.io
provider where common.io FileTransfer operator does not work for
Airflow 2.8.
