support of newer pypy versions

executing was probably in the past tested with pypy-3.5 and pypy-3.6 (tox.ini).
But there are problems with pypy-3.8/3.9/3.10 (I was not able to test 3.7).

```

This https://github.com/15r10nk/inline-snapshot/issues/132 is where I would need pypy support.

@alexmojaki do you know how difficult it would be to use executing with pypy? It looks like pypy support was stopped at some point. Do you know why?
