🐛(react) change most tertiary buttons to tertiary-text

Since the addition of tertiary-text variant, the original tertiary
variant has seen its background color changing from transparent to
greyscale-100, the change has impacted lots of components making
them look odd. So that's why I updated most of old tertiary to
tertiary-text.

Fixes #223
