test: TEMPORARY edits to get tests working for all PRs: NumPy 2.0 cap and turned off Try-It

[jpivarski]

This must not propagate into any non-RC releases of Awkward because upper caps on version dependencies are bad for libraries. But, for the sake of merging PRs into main, we want to see that they pass all tests without NumPy 2.0, at least.

Note for @tcawlfield: when successful, I'll be merging this PR into main and from there into all of the open PRs. Naturally, it should not go into your PR that is fixing #2936. (Your PR can just remove these ,<2.0 constraints, and when it works, it will merge into main and everyone else will get the benefits at that time.)

It got past the issue with package-building, which is what all the other PRs need, but—oddly enough—fails in JupyterLite:

TaskError - taskid:post_build:jupyterlite-pyodide-kernel-piplite:patch

TypeError: expected string or bytes-like object, got 'NoneType'

Trying to pip(lite)-install when the name of the package is None? How did that happen?

Although an error like that shouldn't be fixed by re-running, I'm going to try it anyway in case it's a bad release of JupyterLite that others have noticed and have already put out a patch for.

Just in case, I'll tag @agoose77.
