Update a few random typos

Summary: Found a few typos which could be updated.

Test Plan:
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
|Before|After|
|---|---|
|{F9013208}|{F9013210}|
|{F9013300}|{F9013301}|

I verified the Conduit error message by navigating to `/auth/start/?__conduit__=1`
{F9013289}

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.
