onboarding_steps: Remove hotspot as an onboarding_step.

Earlier, hotspots and one-time notices were the valid
type of onboarding step.

Now, one-time notice is the only valid type.

Fixes #29296.

+* [`POST /register`](/api/register-queue), [`GET /events`](/api/get-events):
+  For the `onboarding_steps` event type, an array of onboarding steps
+  to be displayed to clients is sent. Onboarding step now has one-time
+  notices as the only valid type. Prior to this, both hotspots and
+  one-time notices were valid types of onboarding steps. There is no compatibility

+  this data. Currently, no client other than the Zulip web app uses this.
