Upgrade to NumPy 2.1

[MaximilianHess]

Problem description

We're planning to use NumPy 2.1 in our project due to its performance improvements. However, Gensim currently depends on NumPy 1.26.4. Are there any plans to update Gensim's dependencies to support NumPy 2.1? Currently, attempting to use Gensim with NumPy 2.1 results in a failure.

#3535 was a quickie investigational PR into the effort required for Numpy 2.x support – & it might not get much attention. It's probably not the right place to discuss project plans, if any, for Numpy 2.x support - an issue which might spawn many other PRs, bug reports, &
frequent-questions.

OK, let's make this the discussion place instead of #3535.

@mpenkov @YoungMind1 and @piskvorky I've had a quick look at the numpy update and building the package seems fine and only few tests are broken. I'll give it a go tomorrow and see if I can fix the tests.

I'm also having trouble with my project because it uses spacy which blis and thinc use numpy>2.0 while gensim is still with numpy 1.26.4.
