Bring back min-airflow-version for preinstalled providers (#31469)

In the last wave of providers #31416 we bumped min-airlfow-version to 2.4 and added mechanism to verify min-airflow version is ok while importing, but it turned out that there are cases where installing just old version of airflow (with no constraints) brings the latest version of those providers and causes new installation of airflow to fail. This is far too common to ignore or require to use constraints, unfortunately We do not have min-airlfow-version in the preinstalled providers for one reason only. For some tools that are NOT conforming to standards (such as bazel), having min-airflow-version for those providers causes circular dependency (even though technically dependencies in PyPI can - and often are - circular, because dependencies in Python are not DAG and can contain cycles. This was in response to this issue in 2021 #17795. However, this is really bazel issue, and on top of it - it's recognized as such and being fixed very recently in bazelbuild/rules_python#1188 because there are other packages that have similar problems (pytorch and triton being popular couple). Also Bazel is not that popular in the Python world. Therefore, rather than trying to workaround the problem of bazel, we encourage them to merge and release the fix bazelbuild/rules_python#1166 (comment) and call it out in our installation instructions, that bazel installation might lead to problems like that. If bazel does not fix it, this will only be a problem for Future installations of airflow in a few months most likely. It will not impact current bazel users installing old versions of Airflow (actually they might start having problems now if we do not fix it and yank the 5 providers released yesterday)
