python: bump minimum requirements so they are compatible with 3.12

There are many Python 3.12 issues right now, but a particularly
problematic one when debugging them is that one cannot even use
minreqs.txt in a Python 3.12 virtual environment to test with
locked package versions.

Bump the mypy and wrapt versions to fix this, while remaining
within the realm of versions compatible with Python 3.7.

This requires a workaround for a mypy false positive

    qemu/qmp/qmp_tui.py:350: error: Non-overlapping equality check (left operand type: "Literal[Runstate.DISCONNECTING]", right operand type: "Literal[Runstate.IDLE]")  [comparison-overlap]

where mypy does not realize that self.disconnect() could change
the value of self.runstate.
