CI: tentatively fix hypothesis version

[kmaehashi]

hypothesis 65.5.0 started to infer array api spec version from __array_api_version__ attribute. https://github.com/HypothesisWorks/hypothesis/releases/tag/hypothesis-python-6.55.0
This broke the CI so until we decide the proper value for that attribute pin the hypothesis version to the previous one.

numpy.array_api doesn't seem to have the attribute either.

Hi @honno @asmeurer is this an expected issue?

Hi @honno @asmeurer is this an expected issue?

Yep __array_api_version__ was always expected in the spec but we all forgot about it haha. Wrote a clarifying PR in data-apis/array-api#480.

For the test suite, IMO we should lean on inferring API version from this attribute going forward, and allow users to specify a version to test against. Tracked in data-apis/array-api-tests#20

Ideally you'd have __array_api_version__ = "2021.12" in your Array API namespace... we might still want to magically handle libraries without it, or at least warn on it. Hopefully going to focus on the test suite for the next few weeks generally.

Updated the test suite so it bumps Hypothesis (we need the latest version going forward) and makes libraries missing __array_api_version__ still work data-apis/array-api-tests#144. Made a release too.

Thanks, @honno!

Any updates?

Can we safely use the latest version now?
