Fix learn more link style on projects empty state page

[gtsiolis]

Problem to solve

The projects empty state page contains a Learn more link that does not use the style for default and hover state accordign to to the intial specs.

Workspaces	Projects

Proposal

This can use the same style attributes as the Learn more link in the workspaces empty state page.

gitpod/components/dashboard/src/workspaces/Workspaces.tsx

Line 138 in 99ec2a5

<div className="text-center pb-6 text-gray-500">Prefix any git repository URL with gitpod.io/# or create a new workspace for a recently used project. <a className="text-gray-400 dark:text-gray-600 learn-more hover:text-gray-500 dark:hover:text-gray-500" href="https://www.gitpod.io/docs/getting-started/">Learn more</a></div>

I'd try to do this, if its not done yet (:

[Cahllagerfeld]

I think thats already done

/*index.css*/
 a.gp-link {
        @apply underline underline-thickness-thin underline-offset-small text-gray-400 dark:text-gray-600 hover:text-gray-500 dark:hover:text-gray-500;
    }

{/*Projects.tsx*/}
<a className="gp-link" href="https://www.gitpod.io/docs/prebuilds/">Learn more about Prebuilds</a>

{/*Workspaces.tsx*/}
<a className="gp-link" href="https://www.gitpod.io/docs/getting-started/">Learn more</a>
