Describe the feature that you would like added

Since we are able to adjust the size of the button with enums (and iconSize in ButtonTokens), would be good to also have same way to adjust the size of font inside the button. Otherwise you could have a small button with a huge text. Preferably having this accessible through the ButtonToken as well.

What component or utility would this be added to

React-button (v8)
