Allow the friendly name of an existing MFA factor to be updated/amended

[SteveHawes]

Currently, the friendly name of an MFA factor must be set when enrolling the factor and it cannot be changed once enrolled. This gives the problem that if a user is trying to enrol a TOTP factor, they will need to provide the friendly name before they see the QR code as this is only returned in the result of the enrolment call.

I would like to have an additional method that allows the application update or amend the friendly name by specifying the factorId and the new value for the friendly name. I am currently developing with the Flutter library so the code would be something like:

final AuthMFAUpdateResponse result = await supabase.auth.mfa.updateFactor(factorId: factorId, friendlyName: newValue);

The result could return the old value in case that is required by the developer.

I agree—it's also in the first step so there's no way to glean any helpful fingerprinting to really guess at a name at time of enrollment. I think this would be a welcome UX enhancement.
