JsonConfig: Added brightness properties and dim_ colors

[djinnalexio]

I was making a custom config in VScode and noticed issues with Intellisense.

First, most of the properties for the brightness module weren't valid according to the template.

Second, when using colors, I noticed that bright_ colors are returning the same color as the base ones. I then tried with the dim_ prefix which did give me the other shades which were the darker ones. I got this behavior on both Fedora 40 GNOME 46 and Ubuntu 22.04 GNOME 42.9. I am not sure if the issue is GNOME or Linux-specific which is why I only added dim_ variants to the color list instead of replacing the bright_ ones.

dim_ bright_ are meant to be used by combining standard color keywords. Adding all the combinations will make the list too verbose.

In addition, 256 color and true color can also be specified. See fastfetch -h color for detail. JSON schema is main for suggestion purpose, not validation.

Some colors (like keys) are already in bright mode. Try --bright-color false

I get how it works now, thank you.
