Gutenboarding: the NextButton and SkipButton components throw a console warning for the isLarge props

[andrewserong]

The isLarge prop for the Button component was recently deprecated in Gutenberg. The current usage in Gutenboarding is throwing a console warning wherever the SkipButton and NextButton are used.

Because isLarge didn't appear to be adding any CSS to the styling of the buttons, it appears to be safe to remove these props.

Steps to reproduce

1. Starting at URL: calypso.localhost:3000/new
2. From the intent gathering step, the SkipButton component is throwing a warning due to the isLarge prop being present
3. Continue to the Style step /new/style and the NextButton component is throwing a similar warning

Context / Source

In Gutenboarding, we are basing the user interface in many of the components included in Gutenberg, e.g. the Button component. You can preview these components in the Gutenberg storybook (more on the Gutenberg Storybook setup).

For context, the isLarge prop was removed in: WordPress/gutenberg#23239
The NextButton and SkipButton components are defined in /packages/onboarding/src/action-buttons/index.tsx
These buttons are then used in Gutenboarding in a few places, e.g. in the intent gathering step, and the style preview.

It is appears that it should be safe to remove the isLarge props from https://github.com/automattic/wp-calypso/blob/HEAD/packages/onboarding/src/action-buttons/index.tsx#L44

I thought this would be a good one for @autumnfjeld to dive into :)
