Part of #12401. Breaking into separate PRs so it is easier to review.

Tried in first commit with RhUiExternalLinkIcon but it was a little hard to see compared to ours. Tried Micron version in second commit.

Walkthrough

All references to ExternalLinkAltIcon across the codebase are replaced with RhMicronsExternalLinkIcon. This affects the core MenuItem component, Wizard and deprecated Wizard examples, Card and Toolbar demos, and integration demo components (ButtonDemo, WizardDemo). CardDemos.md also consolidates multiple icon import statements into one.
