Test broken at HEAD

[coryan]

The tests are broken at HEAD. @pitrou figured out what broke them:

Ok, here is a successful build:
https://github.com/googleapis/storage-testbench/actions/runs/6356186515/job/17265417749
Here is the same build failing:
https://github.com/googleapis/storage-testbench/actions/runs/6390316476/job/17343327057

I've tried to find the package differences between them:

Package	Success	Failure
Werkzeug	2.3.7	3.0.0
charset-normalizer	3.2.0	3.3.0
urllib3	2.0.5	2.0.6
coverage	7.3.1	7.3.2
packaging	23.1	23.2

(I would suggest adding a call to pip list at the end of your "install dependencies" build step to make this easier :-))

Given how the error looks like, I would suggest looking at the Werkzeug update for a potential culprit, and perhaps urllib3.
