Create documentation for Pulumi administration

[haydentherapper]

• How do you administer Pulumi? Do you use the CLI or UI?
• Who are the current administrators? Is it a shared account? Or can it be granted to the TSC?
• What's the login for the UI/CLI? Can this be stored in 1password so the TSC has access?
• Same question for the app token

cc @cpanato, can you help create this?

[cpanato]

yes, i can do that, just need to find some free time

FWIW, the GitHub Sync job failed today:

Unfortunately, I don't understand what resource is being referenced, or I would send a PR to fix.
