Remove 3.12 deprecation warning...

regarding the use of pkgdata

NB: I will be investigating what's up with building doctest.

LGTM

I looked at the doctest failure. It looks like we have problems with in mathics core and incompatibility with newer dependencies (scipy?), but I am not sure which ones exactly.

Expect some issues or comments raised in mathics-core.

I looked at the doctest failure. It looks like we have problems with in mathics core and incompatibility with those versions.

Expect some issues or comments raised there.

@rocky, I tested the doctests in my laptop against different versions of Python, and they seem to work properly.

I was seeing the same kind of failure that is in the failure of the github workflows tracker for mathics-scanner here.

For example for this:

2015 ( 3): TEST ArcCosh[0.00000000000000000000000000000000000000]
----------------------------------------------------------------------
Test failed: in Reference of Built-in Symbols / Integer and Number-Theoretical Functions / Hyperbolic Functions
Reference of Built-in Symbols
Exception string index out of range

Adding a len() to the while test addresses this, but we still get the wrong result:
