243 - Update finished page

[Janell-Huyck]

Fixes #243

This PR adds two pieces to the Logged-Out page:

1. A link to Scholar
2. A link back to the Submitter page (login page)

Things to check:

1. Link to Melissa's email goes to the correct address
2. Scholar link opens a new tab going to scholar
3. Return to Submitter page does not open new tab, returns to the login page
4. Any typo's
5. New accessibility issues (Known issue: missing "language" from page, addressed in another PR)

Old version:

New version:

This looks good and matches the screen shot. One teeny tiny suggestion, add an "external link" icon next to the scholar link.
