docs: clarify enterprise settings required for Copilot App to work

Short summary

Affected version or release

v1.0.10

Installation context

mac-os

What happened?

Attempting to use the app against a data residency domain in AU (ghe.com).

I'm getting "retry loading models" after authorisation has completed successfully and starting the first session.

I'm unclear which enterprise settings need to be enabled

• GitHub CLI is one,
• CLI remote control? Or will it fail gracefully with a subset of features available if this isn't set?
• Presumably not 'preview features' anymore now the app is GA?

Same local setup is fine with a personal account.
