Fix type warnings due to mypy version update

github CI was using a newer mypy version which started throwing
excessive warnings about the meta-operations happening behind the scenes
here.

The operations aren't wrong or broken, but because they act to
fix/repair/mutate some of the underlying python object hierarchies
themselves, mypy can't figure out what's happening.

Simplest solution is to ignore the false warnings since we know these
code paths have been working fine for years already.

Also adding mypy to the poetry dev group so maybe we can track mypy
version updates better going forward.
