Prepare knowledge transfer for Sentry Release Github Action

[armenzg]

Another team that is better suited for maintaining this project will take ownership.

This issue will:

• Provide an internal document covering what this team already knows to the next team
• Port all internal documentation to this repo
  • There's a bunch of notes on how to test this action that need verification

Fixes WOR-2986

I've done and recorded the knowledge transfer session.
