docs: add incident.io alert integration

[MikaKerman]

Summary

• Add documentation page for the incident.io alert integration
• Add incident.io to the alerts destination card group and sidebar navigation
• Covers: creating an HTTP alert source, connecting in Elementary, configuring alert attributes mapping, metadata field reference, and deduplication behavior

Screenshots needed

The doc has placeholders for the following screenshots:

1. An Elementary alert shown in incident.io
2. incident.io "Create alert source" page with HTTP selected
3. Alert source details page showing the alert source URL
4. Elementary environment page — incident management connect card with incident.io selected
5. Elementary incident.io connection dialog with the URL field
6. incident.io alert source "Edit attributes" screen with an Elementary alert payload

Test plan

• Preview docs site and verify page renders correctly
• Verify sidebar navigation shows incident.io under Alerts & Incidents
• Verify integration card appears on the integrations overview page
• Add screenshots and verify they display correctly
