Bump SDK constraints for pub (#143)

natebosch · web-flow · commit b23d0d2f9686 · 2020-11-03T14:12:05.000-08:00
Use a 2.12.0 lower bound since pub does not understand allowed
experiments for earlier versions.

Use a 3.0.0 upper bound to avoid a warning in pub and to give some
flexibility in publishing for stable.
