Removing secondary class from the main CTA button to give proper weight.

[jordanhailey]

Per #4197, same code as #4286 with shorter branch name to avoid build error.

By toggling the css classes on the browser I was able to confirm the secondary class is the "muted" color, it is a grey background with darker grey text. By removing that class in the browser I could test that the default styles applied on buttons are the green background and white text as pictured in the comment at #4197 (comment)

NOTE: I couldn't actually verify the change was applied to the button on the "not authorized" screen due to the restrictions placed on the dev environments, not being able to add a workspace. Instead, when trying to add a workspace I ended up receiving the following message:
