fix: RedshiftDataHook and RdsHook not use cached connection

[Taragolis]

After finding in this PR: #24057 (comment) I've checked other AWS Hooks which not use cached conn property and found two hooks RedshiftDataHook and RdsHook

Add to AwsBaseHook generic connection, so it won't required anymore overwrite conn property

Type hinting still work in IDE (PyCharm) after changes

LGTM. @ferruzzi @o-nikolas WDYT?

The PR is likely OK to be merged with just subset of tests for default Python and Database versions without running the full matrix of tests, because it does not modify the core of Airflow. If the committers decide that the full tests matrix is needed, they will add the label 'full tests needed'. Then you should rebase to the latest main or amend the last commit of the PR, and push it with --force-with-lease.

I've just wondering that in amazon-provider boto3-stubs packages defined in main package requirements is it better also move to mypy_dependencies section? I think it won't required in Airflow cluster, only for developing.

airflow/setup.py

Lines 201 to 202 in dfdf8eb

	'mypy-boto3-rds>=1.21.0',
	'mypy-boto3-redshift-data>=1.21.0',

Not really. Mypy Section is for "generic" mypuy dependencies that are required for Arflow "core" (in development but still). We are likely going to reshuffle deps soon, preparing to splitting providers from Airlflow core and the "amazon" specific dependencies will land in setup.py of amazon provider eventually - they will be completely removed from the "airflow" setup.py.

So it's better to keep them where they are for now. We are going to likely make also each provider to have their own [devel] extra when we split out (or similar), so they should likely go there.

soon = few months from now. I am gearing up to write detailed description/AIP of what's needed there (I will ask for help on reviewing and finalizing when I get there).
