Relax CI constraint on numpy<1.25#11020

Conversation
The major problem in NumPy 1.25 transpired to be that particular versions of Apple clang (including the one used in Numpy's wheel-build CD pipelines) produced non-deterministic code from new SIMD routines for complex multiplication. This in turn destabilised our `Isometry` decompositions, which caused major correctness problems. As of Numpy 1.26.1 (released 2023-10-14), that SIMD code now decays to the scalar form if the compiler was known to be buggy, which restores the previous behaviour.

Removing the restriction on the numpy version has introduced some non-determinism to some of the unitary synthesis tests that is causing a flaky failure in CI. This commit reverts the version cap removal to unblock CI. In parallel we should debug the source of the instability causing the test to fail so we can run CI using the latest version of numpy. This reverts commit fb8a69d.
