Launchpad Navigator: Remove from Calypso

[tyxla]

Proposed Changes

Remove the disabled Launchpad Navigator from Calypso.

Why are these changes being made?

It's been over a year since the Launchpad Navigator meetup project was shelved.
It was still then considered that it's uncertain it actually solves a real user problem, and I don't see any updates on this. Should we want to bring it back, it's quite straightforward to revert this PR.
With that in mind, we should be able to remove it altogether.

See paYKcK-3CA-p2 for context.

I spotted this while reviewing #98333 (cc @jsnajdr) and found it's a good opportunity for cleaning up dead code, rather than refactoring the LaunchpadNavigator data store away from generators.

Testing Instructions

• Verify Calypso builds well and all checks are green.
• Smoke test the Launchpad and verify it works well.
• Verify in one of the steps that disable the launchpad that it still disables it correctly.
