Adjust enum reprs conditional from Python 3.10 to 3.11

I don't think a changelog fragment is necessary: It changes tests only, no chnagelog fragment was even in the original commit that introduced the condiitonal.

FWIW I'd prefer a revert of those changes - according to the discussion, there are potentially incompatible changes planned for 3.11, and there will be a PEP written first - so at this point, it seems very speculative to me to already have our tests handle the new format when we have no idea how it'll end up looking like.

Fine by me ;)

Alternative approach (full revert) in #8896

Agreed, thanks for pointing that out. I thought the changes would land in 3.11, so why not just adjust the code? But given more discussion will certainly follow, then I agree completely.

Closing in favor of #8896.
