Update an old SSH redirect URI when editing a bot's SSH keys

Summary: See PHI79. When you edit another user's SSH keys (normally, for a bot account) we currently redirect you to an older URI.

Test Plan:
- Viewed a bot's profile page.
- Clicked "Edit Settings" on the Manage page.
- Went to "SSH Keys".
- Uploaded an SSH key.
- Before: redirected to a 404 after finishing the workflow.
- After: redirected to the same page after the workflow.
