Update a few random typos
Summary: Found a few typos which could be updated.
I tested the Configuration page change by navigating to /config and verifying the page title set in the browser as well as the page title text on the page
I verified the Conduit error message by navigating to /auth/start/?__conduit__=1
The CircleCI error message was not verified due to the involvement of testing with CircleCI however the change is very minor and has very little risk of impacting any functionality.
