Simplify pr workflow to require 2 approvals on all PR's (#74)

Simplify pr workflow to require 2 approvals on all PR's

## Call Outs
All PR's will need 2 approvals from the commitee for this check to pass.
A more intelligent approach is on the way, but till then all PR's will
need 2 approvals.

This is done to prevent sneak attacks where someone gets approval for
non-std related changes, and after approval, they make changes to the
std files.
