Changes to PR wait time and approval checks

[mmarchini]

If https://github.com/nodejs/node/pull/33879 lands the checks should be changed to:

• Require only one approval by default
  • Recommend (without blocking) to wait for a second approval
• Drop wait times as requirements (we can still add a suggestion to wait if the PR lands before 48h, but it should return success code and shouldn't block --yes)
• Check if 48h passed since the wait-for-feedback label was added

As a workaround for now, we can add a .ncurc file to nodejs/node, which will remove the wait time requirements, but handling the more fine grained cases suggested above probably makes more sense.

https://github.com/nodejs/node/pull/33879 never landed, we can probably close this.
