Adding primary and secondary text colors

[evanaze]

Description

Franken-UI doesn't match UIKit's functionality with text coloring. It's missing the following classes:

• .uk-text-primary Add this class to emphasize text with the primary color.
• .uk-text-secondary Add this class to emphasize text with the secondary color.
• .uk-text-success Add this class to indicate success.
• .uk-text-warning Add this class to indicate a warning.

Evidence:

From Franken-UI documentation

From UIKit documentation

I use the colors for text and links a lot via tailwind (for example a link might be uk-link text-primary hover:text-primary-focus underline). So having the color options described in this PR built into FrankenUI for both text and links would be useful to me as well :)
