[RAINBOW EFFECT] Added methods to get HSL components from Color

[IDEDARY]

Changes

Added methods to Color enum to retrieve Hue, Saturation and Lightness values.

Why?

As you probably know, to create a color that iterates over the color spectrum (rainbow effect that can be seen on LED keyboards, PC components, etc..), you need to mix the color from Hue, Saturation and Luminosity. Bevy already supports multiple color formats, but provides only 4 methods of retrieving components for RGBA. Nothing like ".get_hue()", so I implemented them with all their variations that RGBA has.

Now we can do true rainbow color blending (Example is a button hover effect): Discord Showcase, Video download

(note that it segfaulted at the example and that's a known problem with CI right now, but you also have CI validation problems that need to be fixed)

Yeah I saw the discussion on Discord about it. I also added the interactive links to my comments as you suggested.

I also kind of noticed that this fixes the same issue as #7759, so I guess cart can decide which PR he likes more. The other PR has more specific naming than mine as I tried to be consistent with existing code.

I approved both because I'm fine with both personally (I know it doesn't help much ^^')

This is fine as is: we can clean things up later if people care enough.
