Improve documentation on how to enable/disable features via CLI arguments

Can't figure out how to, e.g.

* disable notification delegation (enabled by default, wizard doesn't ask about it)
* enable alpha dependencies (disabled by default, wizard doesn't ask about it)
* enable first run flag and pass the `queryParameterName` value (disabled by default, wizard doesn't ask about it)
* enable AppsFlyer and pass the AppsFlyer ID value (disabled by default, wizard doesn't ask about it)

via CLI arguments during init? 🤔

If it's possible, could you please share complete command lines (with all arguments)?

Editing the `twa-manifest.json` in a text editor by hand and running the `bubblewrap update` command after that doesn't seem like a good idea.

BTW, is it possible to enable the following features via CLI arguments (so the wizard doesn't ask about them later)?

* enable location delegation (disabled by default, wizard asks about it)
* enable Play Billing (disabled by default, wizard asks about it)

If so, how?
