apport should prevent crash reporting for unsupported python versions

[Brian Murray]

The following bucket in the Ubuntu Error Tracker was brought to my attention because a package update stopped phasing because of it.

https://errors.ubuntu.com/problem/51d4468e0e9096398f852e3aed0e51658b6ca603

Looking at the individual crashes, e.g. https://errors.ubuntu.com/oops/2b3117f0-b6ea-11ee-b9e6-fa163e171f02, we can see that the InterpreterPath is /usr/bin/python3.9 and that this also appears in Python3Details.

I don't see an UnreportableReason in the report so these would likely get sent to Launchpad also. Anyway, I don't think these types of crashes (using an unsupported python version) should be reportable because there isn't anything we as Ubuntu Developers can do to resolve this problem.
