[red-knot] mypy_primer: Fail job on panic or internal errors (#17389)

## Summary

Let the mypy_primer job fail if Red Knot panics or exits with code 2
(indicating an internal error).

Corresponding mypy_primer commit:
astral-sh/mypy_primer@90808f4

In addition, we may also want to make a successful mypy_primer run
required for merging?

## Test Plan

Made sure that mypy_primer exits with code 70 locally on panics, which
should result in a pipeline failure, since we only allow code 0 and 1 in
the pipeline here:
