Update hub page from "Enterprise" to "Business"

[mikehoffms]

Rendered hub page for review:

• Microsoft Edge documentation
  • ~/index.yml
  • Internal preview: https://review.learn.microsoft.com/microsoft-edge/index?branch=pr-en-us-3503
  • External preview (raw): https://github.com/MicrosoftDocs/edge-developer/blob/user/mikehoffms/hub/microsoft-edge/index.yml
  • Before/live: https://learn.microsoft.com/microsoft-edge/
  • Changed topmost section & Microsoft Edge for Business section per "Microsoft Edge documentation homepage changes July 25.docx".
    • Instead of topmost section linking away to landing page for Business, scrolled down to that section of hub page (like for Dev section).
    • In topmost section, reseq'd cards within rows.
  • Improved itemType values (icons & headings for doc-type).
    • Updated from "learn" to "training".
  • In Help and Support section, improved verbose descriptions.
  • Added comments, to support Maint & doc-design.
