Fix tests to be compatible with urllib3 2.0

[pquentin]

Somehow some cassette files were incompatible. I also tried adding urllib3 2.0 tests in CI, let's see how that goes.

[pquentin]

The urllib3 2.0 tests are fixed by urllib3/urllib3#2998

Is the company issue in the toolbelt or in betamax?

[pquentin]

What is the company issue sorry? If you mean urllib3/urllib3#2999 it's a totally different issue

[sigmavirus24]

*compatibility

If rerecording the cassettes makes a difference it makes me think the compatibility problem is in Betamax fundamentally

[pquentin]

Maybe it is. I don't know, I have to admit I stuck with the first thing that worked. But I did not have to change most responses, so this is definitely fishy. I would have to investigate more and understand how Betamax works.

patches from this pull are needed for tests to pass on master branch when using urllib3 2.0. I have a yocto setups and I can confirm the failures

without these patches.

Thanks for confirming! However I'm not sure the approach is correct and still works on 1.26.x. We would have to fix our CI to tell.
