Not redirected to Backup Codes after enabling WebAuthn

[iandunn]

1. Wipe out all settings/providers so you start fresh
2. Enable TOTP. You're redirected to Backup Codes
3. Wipe out all settings/providers so you start fresh
4. Enable WebAuthn. You're not redirected to Backup Codes

For consistency, I think we should add something like this to WebAuthn

wporg-two-factor/settings/src/components/totp.js

Lines 25 to 28 in fa4c81b

	const afterTimeout = useCallback( () => {
	setSuccess( false );
	navigateToScreen( 'backup-codes' );
	}, [ navigateToScreen ] );

#286 might resolve this.

Alternatively, given you can enable multiple keys, perhaps simply a notice at the bottom of the keys screen suggesting "All done? Set some Backup codes".

This is IMHO one of the reasons why it's common to be presented with the backup codes prior to setting up any 2FA methods.
