Update ignore for latest mypy (backport #192)

[mergify]

Summary

Nightly CI is failing following mypy 1.11 release. It seems that the detected error is now different. I changed things to be compatible with the prior version which ends up with two ignores and and unused ignore with each so that the other version does not raise the specific error does not raise another about it being unused.

What with all the suppression there now I can't help but think the code ought to be fixed in some way. But for now it works, i.e. passes unit tests etc. so this simply updates things for CI to pass too.
