I see that this version has loosened up the dependency on the protobuf version. This is great. We can almost upgrade now. However, can you do the same with docker? I am not sure it needs to be '<5'. Version 5 did not change any api as far as I know, only dropped support for python 2.

I'd like to also see support for both docker 4 and 5, there are no incompatible APIs between the two. In fact I did a similar change in the Flyte repo recently and there weren't any issues: flyteorg/flytekit#1536

Would be great to set it at least to docker>=4.0.0,<7.0.0
