Doc: use 'ellipsoidal' to refer to the ellipsoidal formulation (to be opposed to the spherical one)
Instead of 'elliptical'. Was suggested by @cffk in https://github.com/OSGeo/PROJ/pull/2030#issuecomment-596132341 An elliptical projection is a projection whose global shape fits inside an ellipsoid, like Mollweide. At least according to https://www.merriam-webster.com/dictionary/elliptical%20projection and https://en.wikipedia.org/wiki/Mollweide_projection
