Closes #28888

Reason for this change

Currently, we just check for if a minimum bootstrap version is needed for a functionality and give a warning. But, we do not check the bootstrap version of the stack itself. This gives a confusing warning for upgrading to a bootstrap version (example: version 8) when the stack bootstrap version is already higher than the recommended version.

Description of changes

We cannot know successfully what the bootstrap version is in the AWS account without the lookup role. We are getting this warning while trying to assume the lookup role and failing to assume it.

I am removing upgrade related warnings since we are emitting them without any confirmation of the user's account bootstrap version. This will lead to confusion. Instead, I am trying to make some of the existing error messages more clear.

Description of how you validated changes

Updated unit tests.
Will run this through test pipeline.

If we are unable to assume the lookup role and are not looking for the bootstrap version in SSM of the user's account, then there is no way we are sure about this recommendation. And, we should not just be recommending this without knowing it for a fact that they are on an older version of bootstrap.

We already error out if the user is using an older version of bootstrap than the recommended version.

This one has an invalid bootstrap version (1 when >= 5 was expected) and an upgrade message should be emitted here

This is weird. Without successfully assuming the lookup role, how will we know what bootstrap version is in SSM. Maybe cached? Taking a look

But, if we are able to assume the role, we do throw in such scenario instead of a warning: https://github.com/aws/aws-cdk/blob/vkukreja/doc-update/packages/aws-cdk/lib/api/deployments.ts#L546-L549

So it was throwing the expected error but since we catch it and do nothing, it will only show up if we have --debug flag enabled. I believe it needs to be shown and hence adding it with error
