chore: increase try-it version of Awkward to 2.6.4

[jpivarski]

When I check the Pyodide console currently available online, the current version of awkward-cpp is 33:

>>> import awkward_cpp
>>> import pkg_resources
<console>:1: DeprecationWarning: pkg_resources is deprecated as an API. See https://setuptools.pypa.io/en/latest/pkg_resources.html
>>> pkg_resources.get_distribution("awkward-cpp")
awkward-cpp 33 (/lib/python3.12/site-packages)

This is a little more recent than the awkward-cpp 26 that the Try-it! page is currently pinned to (because if we didn't pin it, it wouldn't get the latest awkward-cpp but would get the latest awkward and there'd be a conflict). Updates are good things, so let's update (from November 2023 to May 2024).

The latest awkward version this corresponds to is 2.6.4:

awkward/awkward-cpp/pyproject.toml

Lines 8 to 10 in 836b28a

	[project]
	name = "awkward_cpp"
	version = "33"

This PR ought to give me a "View Deployment" button (it's also a test of that), which I'll want to test before committing to change the documentation. The worst thing is when a public Try-it! page is broken—even being out of date is better.

No, this has the wheel spin forever, but in the Javascript console,

You can use `await micropip.install(..., keep_going=True)` to get a list of all packages with missing wheels.

@jpivarski the thing to watch out for here is the version of pyodide that is pulled into the HTML page. Before, we built the WASM wheel ourselves and pulled it in, but now that we rely on the prebuilt distribution, we can only move as fast as the distribution release cadence.

It looks like we can bump to whichever version of Awkward is in 0.26.2 (see https://github.com/scikit-hep/awkward/blob/3d031ca2482c6d9f94f1153aef53e3b772b2406b/docs/_static/try-it.html#L76C58-L76C65)
