feat: Remove the urllib3 pinning

[sathieu]

What type of PR is this?

/kind feature
/kind regression

What this PR does / why we need it:

The PR removes the version pinning for the urllib3 library.

Same as #2461, for release-34 branch

Which issue(s) this PR fixes:

Fixes #2458 #2424

Special notes for your reviewer:

Does this PR introduce a user-facing change?

We no longer pin the `urllib3` version.  
`urllib3` 2.4.0 introduced stricter certificate checks on Python 3.13+, which may trigger: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Missing Authority Key Identifier

This only affects clusters (version <=1.16) with outdated or misconfigured certificates (e.g. old AWS EKS versions). Please update the Kubernetes cluster certificates.

Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

It should probably take #2477 into account?

2.6.1 has been released which reverts the breaking change.

Yes, to be clearer my suggestion is to yank/disallow 2.6.0 in the requirements

I wonder when it will be released...
