Fixed some accessibility, and moved homepage things around. (#22832)

Addresses #21638

Changed install to genai, moved genai section up, accessibility changes
in docs/install.

Still todo (another PR, soon to come):

- Change theme for accessibility
- Change videos linked on homepage
- Update homepage content to more closely reflect current ORT status.
