Support urllib3>=2

[arnaudsjs]

To add some context to this ticket: this project has an upper bound on the version of urllib3 (see here). This makes the cloudsmith-cli package incompatible with packages that require urllib3>=2. An example of such a package is types-requests. Since urllib3 is a very popular library, this is bound to get worse as more and more packages will migrate to urllib3>=2.

Therefore I think it would be good if the constraint could either be relaxed (in case the package is actually compatible with urllib3>=2) or if it could be made compatible if it isn't already. They have a migration guide available here.
