[PROPOSAL] Disable CI on draft PRs

[HoloTheDrunk]

Context

Draft PRs are by definition not ready and running CI on them creates a lot of noise (and wastes resources).

Expected Behavior

The CI should skip draft PRs.

Actual Behavior

The CI runs everything on draft PRs.

Possible Cause/Fix/Solution

if: github.event.pull_request.draft == false
