Update apple links in 7.0

[markavitale]

Pull request checklist

• Addresses an existing issue: Fixes #0000
• Include a change request file using $ yarn change

Description of changes

The fluentui-apple repository recently updated its default branch to be named 'main'. Since there are some links to the old default branch ('master') in our documentation, update them to be correct. There were a few other minor changes due to some refactoring in the fluentui-apple repository.

Note this was already merged into master with #16978, this is a cherry-pick to the 7.0 branch to update the current website.

Focus areas to test

Ensure the links properly take users to the new default branch of the Microsoft/fluentui-apple GitHub repository. Tested by running the website locally and clicking through the links.
