Outline projects, groups, and initiatives that can be supported on the Drupal collective

Transferring as a related issue to #3377002: Enhancing the Drupal Association's Mission through Open Collective →

Removing the links to projects on the Drupal Contribution collective as we'll be transferring over to the Drupal collective once it exists.

Moving this to the Innovation project (or the closest thing we have) as the issue for the top-level Drupal collective is here...which should be key for Drupal growth and innovation.

I think it would sense to add Starshot to the list of projects on Open Collective. Maybe even be at the top given priority?

Not sure if the admins (of https://opencollective.com/drupal) were able to discuss at DrupalCon, but setting up projects for Starshot → and other related initiatives (like what Dries referenced in this summary post) would eventually surface Drupal in Open Collective's open source ecosystem provide additional visibility, increase funding, and grow/diversify the contributor base for the initiatives and Drupal.

From an implementation standpoint, it will primarily rely on the Project Browser → and Recipes → initiatives, while also incorporating the Experience Builder initiative.

Closed as not needed, but can be referenced, reopened or recreated later if/when Parent issue → is approved.
