fix: update cppyy module

[ianna]

cppyy module relied on ak._utils to check the version.
Also we need to import cling. I'm not sure this is the best place, but it works:

import awkward._connect.cling  # noqa: F401

@agoose77 and @jpivarski - preparing for PyHEP I've discovered that cppyy test would fail. I wonder if this patch can be integrated in the next release asap. Thanks!

@ianna I presume we need to install cppyy from source to obtain the supported version? Perhaps we should add a CI job to do this.

When obtaining cppyy from Git, do you locally need to bump the version to 3.0.1?

Yes, ak._util.parse_version was removed in 11e61b6#diff-5b25481afa0bba148a54d46dfc93af8141dfa50dcb399c55bb7df34f3af40f64

The dangerous-looking

import awkward._connect.cling

happens inside of the non-inspectable ak.Array.cpp_type property, so it's safe.

I think this is ready to go and will merge it.

Thanks for merging this @jpivarski, I missed Ianna's reply!
