The third and fourth welcome tips reference actions that are not always possible

[johnbillion]

Describe the bug

The third and fourth welcome tips instruct the user to click the Preview and Publish buttons. If the user has chosen not to insert any content, and instead simply follow the tips, then these actions are unavailable and the user is pointed to two disabled buttons.

Tested with WordPress 5.0 RC.

To Reproduce

Steps to reproduce the behavior:

1. Ensure the localStorage in your browser is clear for your domain, so that tips appear (related: Tips: status should be user-based not browser-based #8052).
2. Open the block editor.
3. Click See next tip on the first and second welcome tips.
4. Observe that the third tip points to a disabled Preview button.
5. Click See next tip.
6. Observe that the fourth tip points to a disabled Publish button.

Expected behavior

The welcome tip flow should be tweaked so that a user is not instructed to click a disabled button. Maybe the tips should be dynamic based on whether the user is adding content, or simply following along with the tips. Not sure on the best approach.
