LUCENE-10508: Fixes some failures where a GeoArea is built with degenerated
latitudes (#804)
Fixes some edge cases where GeoArea were built in a way that
vertical planes could not evaluate their sign, either because the planes
were the same or the center between those planes was lying on top of one
of the planes.

> I hit a failure when trying to build a GeoArea using the GeoAreaFactory. The
> issue seems to happen when you have an almost degenerated minLatitude and
> maxLatitude and you are close to the poles. Then you might hit the following
> exception"
> {code}
> java.lang.IllegalArgumentException: Cannot determine sidedness because check
> point is on plane.

> double maxX = Math.nextUp(minX + Vector.MINIMUM_ANGULAR_RESOLUTION);

> double maxY = Math.nextUp(minY + Vector.MINIMUM_ANGULAR_RESOLUTION);
> assertNotNull(GeoAreaFactory.makeGeoArea(PlanetModel.SPHERE, maxY, minY,
> minX, maxX));
> }
