https://geminicli.com/docs/get-started/installation/

What is the problem?

Audit the documentation and identify pages that have multiple ways of doing the same thing, for example, different commands on different OS's to install Gemini CLI. Update these pages to be .mdx files that use the tabbed widget component.

What did you expect to happen?

Pages are currently difficult to read as different methods to accomplish the same thing are presented serially.
