Create an initial fundraising campaign

Centralizing all projects and initiatives related to some aspect of sustainability (including sustaining the Drupal project and community) under
the umbrella of the new Sustainability team!

Will revise and refine as we get the team up and running.

Moving as this is a subtask of #3325045: Community Enabler Initiative → . As the latter overlaps with other active projects and initiatives, we may end up consolidating and closing out this initiative (and this task!).

Looks like https://opencollective.com/drupal-contribution and https://www.drupal.org/project/drupal_contribution → exist, but may be abandoned

I also see that https://www.drupalcontribution.org/ exists

This was a child task for an outdated initiative https://www.drupal.org/project/innovation_ideas/issues/3325045 →
