✨(frontend) add french touch effect

Enhanced the FaceLandmarksProcessor to include
a new 'french' effect, allowing users to add
a beret image to detected faces. Updated the
EffectsConfiguration component to toggle this
effect and modified localization files to
reflect the change from 'mustache' to 'french'.
