Updated link colors to meet WCAG color contrast guidelines. #2976

This fixes a color contrast issue with a handful of links throughout the React Native website. These links were previously rendering as --ifm-color-primary (#06bcee) on white, which is a contrast ratio of only 2.22:1, failing all WCAG criteria.

https://webaim.org/resources/contrastchecker/?fcolor=06BCEE&bcolor=FFFFFF

This PR changes the link color to be #357da1, which changes the color contrast to 4.56: 1, passing WCAG AA criteria.

https://webaim.org/resources/contrastchecker/?fcolor=357DA1&bcolor=FFFFFF

This change is only made when in light mode, since in dark mode, the original color against black has good contrast (9.43:1), and the new one is lower contrast (4.59:1).

Screenshots of all the affected UI in light mode, dark mode, and when hovered are below.

Thanks for making changes @blavalla! They look good, my question is how did you think to update these? I'm not sure how to scale this so we don't regress on color contrast guidelines.
