[pylint] Fix consider-using-sys-exit, use-yield-from, and implicit-str-concat

[Pierre-Sassoulas]

Follow-up to #12172

[bluetech]

IMO, the pointless-x-statement changes don't really improve things, I'd leave it out (but I don't feel strongly about this).

I think there is some confusion in the commit subject [pylint 'implicit-str-concat'] Use zip when iterating on two iterators.

Other than that LGTM, thanks!

Removed (the benefit would be to be able to see new violations without having low values warning, I agree that the diff is not much better). Either ruff did not catch them or they filtered this when in a pytest.raises / unitest.assertRaises, which make sense.

Yeah, nice catch, probably reused an old message without updating properly, fixed.
