[ENG-11658][eas-cli] Add --no-channel flag for update and rollback to embedded

[quinlanj]

Why

When users create an update, we make sure that the branch they publish to is linked to a channel of the same name. However, this behaviour is not always desirable. For example, in the development usecase where someone is trying to load their update in the dev-client, a channel is not necesary. Users will either navigate to the update they want in the dev client menu or via a preview QR code.

When we've interviewed users who use the dev client/qr code flow, they are always running eas delete:channel after the eas update command.

How

This PR adds a flag, --no-channel for the development usecase. This prevents a channel from being automatically created.

Test Plan

• [ ] new tests pass
