bump conda-forge-ci-setup version & conda-build lower bound

[h-vetinari]

Discussed in core call today; the conda-build used here is constrained by the old ci-setup; update to what the rest of our infra is using as well.

First time I'm doing an upgrade of staged-recipes, please let me know if I missed something.

Hi! This is the friendly automated conda-forge-linting service.

I was trying to look for recipes to lint for you, but couldn't find any.
Please ping the 'conda-forge/core' team (using the @ notation in a comment) if you believe this is a bug.

Isn't there a conda mambabuild command we need to change too? I thought we couldn't use boa anymore now?

I looked around, but all I could find was that build_all.py calls the conda-build API directly; there was no direct callsite to conda mambabuild or conda-build that I found.
