Add project labels

[AetherUnbound]

Description

This PR adds a few new project-related labels, based on a discussion in our Make WP slack about project-related automation.

The labels are:

• 🧭 project: thread - this reused the existing project label so our project tracker still works
• 🧭 project: proposal
• 🧭 project: implementation plan

Nice!

The new labels are good, but we'll also need a label for general discussion PRs that aren't related to projects to automatically add those the discussion board as well. For example the #887 PR was a discussion that followed the decision-making process but is not related to a project so is neither a project proposal nor implementation plan.
