OEP-1: Updates for clarity & current realities

[sarina]

Problem

OEP-1 has lots of outdated information. Further, it's wordy and not very clear/approachable to new people coming on-board to their first written OEP or Arbitration role. @kdmccormick and @sarina are proposing a set of changes - they will write up changes individually and make separate PRs, requesting comment from the community on each.

Thank you! 😄

I followed https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue to link my commits to my issues. My hope 🤞🏻 🤞🏻 🤞🏻 is that merging my PRs will automatically close my issue which will automatically tick the box next to the issue on this issue.

Update: Merged in all my OEP-1 changes. When I next have downtime, I'll tackle openedx/tcril-engineering#133
