BUG: GH34677 Roll forward asv benchmark environment to py3.8
Partially closes #34677 
I think we could also just remove this entry altogether Just tested and that works for me as well. You think that's the better route to take? Yea I think so We need to verify that changing this won't cause a break in the timeseries at https://pandas.pydata.org/speed/pandas/. How do we do that? I have another PR pending that needs benchmarking  I'm not sure what conditions cause asv to consider it a different environment.

Hopefully that isn't blocked by this issue. You can make the changes locally and run the ASVs. Oh duh yeah thanks I think this will cause a break in the timeseries (in a similar way as the cython version pin caused a new timeseries, see the two colors at eg https://pandas.pydata.org/speed/pandas/#algorithms.Hashing.time_frame), but I don't think there is a way around that? We need to do this update at some point, so the question is maybe if we are ok with doing it now.

 Even if this breaks the time series I would be OK with doing it. Maybe after the next release so we get a clean delineation? Yes, I think waiting until after the release sounds as a good idea
