[SDK] Allow supplying a password to the `LoginWizard.resetPasswordMailConfirmation` step

[ouchadam]

Description

Currently the SDK LoginWizard expects both the email and password to be supplied when resetting an account password. This is specific to Element's current reset flow rather than dictated by the spec/api.

The new FTUE reset password flow separates the email confirmation and new password confirmation steps, matching the reset password endpoints.
