FEM: Some constraint descriptions regarding geometry selection are misleading

[FEA-eng]

Is there an existing issue for this?

Problem description

Several FEM constraints (like fixed or force) use the following description for the geometry selector: "Select multiple face(s), click Add or Remove". This is misleading because most of them accept other types of geometry elements as well. This was recently reported by a user here: https://forum.freecad.org/viewtopic.php?t=87485

Moreover, the description suggests that it's necessary to select multiple faces which is of course not true.
