Renaming asv setting build_cache_size

[datapythonista]

The CI job that is checking that the benchmarks don't break is reporting that an asv setting has been renamed.

I think we've got a server where we run the benchmarks, not sure if we replicate the environment there at every run from environment.yml. Otherwise I guess we should do it manually before merging this.

@TomAugspurger I think you manage that server? does this make sense?

I don't think so. I think ASV has it's own way of building the environment from the matrix of dependencies.

[datapythonista]

Looks like the benchmarks are failing, the error here is unrelated to this PR, I also saw the same error in #26414. We don't see in other PRs, because we only check the benchmarks when something inside asv_bench is modified, and I guess the failure was produced by changes in pandas.

Will check which change broke it, and open an issue.

[jreback]

@datapythonista is this still needed?

[datapythonista]

@jreback my understanding is that a future version of asv will remove the renamed setting, and I don't know if our benchmarks will break or the current setting will be ignored, but I think we should make this change before that.

thanks @datapythonista
