werkzeug compatibility

[loqs]

There no longer appears to be an issue with werkzeug 2.1.0 as no test failures are produced using 2.2.3.
Allowing up to the latest release (2.3.7) of werkzeug would be preferable but that produces test failures.
I do not know which project the test failures should be addressed.

Test results for httpie/cli 2.2.3 with
werkzeug 2.3.7
