fix(ProgressBar): light theme text color

[ricardoasmarques]

Why?

ProgressBar text color in light mode is very similar to the background color, making it very hard to read.

Before

After

How?

Progress bar relies on mix-blend-mode: difference which works better on high-contrast colors, so I've created a new --click-progressBar-color-text-default token and populated it with the following colors:

• Light: white
• Dark: same color that was already being used before

@gjones Is these tokens available in figma and we might need to correct it there and sync it

[DreaminDani]

Nice. even works when it's cutting through the text 😎

Tagging @gjones as a reviewer since he has to update the figma tokens manually. I'd love to get him out of being the bottleneck for this but we can do that later 😓
