CI: Test with latest matlab runtime

[MridulS]

Trying to debug #669

[MridulS]

huh, it has nothing to do with matlab as those tests are skipped anyway.

This is actually an issue with the FMA instruction set on ARM64 machines!! It is too acurate.

On my ARM machine

In [1]: import scipp as sc

In [2]: a = sc.vector([-0.5620126808026259, -0.1798933776079791, 0.8073290031392648])

In [3]: nxa = sc.cross(a, a)

In [4]: nxa
Out[4]: <scipp.Variable> ()    vector3  [dimensionless]  (-1.33772e-17, -2.53988e-17, 5.31669e-18)

on VISA x86_64

In [1]: import scipp as sc

In [2]: a = sc.vector([-0.5620126808026259, -0.1798933776079791, 0.8073290031392648])

In [3]: nxa = sc.cross(a, a)

In [4]: nxa
<scipp.Variable> ()    vector3  [dimensionless]  (0, 0, 0)
