Bump numpy~=1.26.4

[ddelange]

fix flaky timeout on master by requiring recent numpy which has wheels available for musllinux_aarch64

NumPy follows SPEC 0, which means Python 3.8 support got dropped in NumPy 1.25.0.

NumPy 1.24.4 is the last release that supported Python 3.8.

And I'm not sure we should bump the dependency for all just for a build issue. Can we only do this when we build the wheel... i guess we should also build to the latest possible.

Why is it flakey btw?

[ddelange]

you're right, this PR doens't make sense in the current state.

on master there is only one failing wheel build: https://github.com/vaexio/vaex/actions/runs/10835977160/job/30068700570

due to oldest-supported-numpy selecting a version of numpy for which no wheels are available. building numpy from source under QEMU takes forever, so we're hitting the builtin github actions 6 hour timeout (which can't be increased)

[ddelange]

it's flaky: the scheduled run on master was successfull: https://github.com/vaexio/vaex/actions/runs/10841954610

we could simplify our lives if we don't add support for musllinux_aarch64 wheels in the upcoming release. thoughts? 👍 👎

Only manylinux_aarch64 ? I'm fine with that!
