Run 'mark-committed' from 'arc land'

Summary:
  - Remove "new and experimental" because arc land is super awesome and great.
  - Run the 'mark-committed' finalize workflow after pushing for untracked repo
setups.

Test Plan: Ran "arc mark-committed --quiet --finalize 123". Will run "arc land"
on this. so lazy
