[Dimmer] Hover Dimmer

[GammaGames]

Feature Request

Description

While text overlays were implemented here, I think a css-only variation would be welcome so users do not have to use the transition module for a basic fading text overlay.

I also think, if implemented, it would be nice to show an example in the variations section for image, because dimmer is not the section I would have looked to find the text overlay feature.

Example

It can be implemented (roughly) with the following css:

.ui.hover.dimmer {
  display: flex;
  transition: opacity .25s ease-in-out;
}

.ui:hover>.ui.hover.dimmer {
    opacity: 1;
}
