Resolve "Remove routes that we do not use anymore"

_Originally opened at !4059 by @strzibny._

- - -

## What does this MR do?

> I tried to clean up the routes as mentioned in #14584
I used the following script and manually verified the changes: https://gist.github.com/strzibny/4ccbda7dcf67ef6719dcb047014e1ea7
After this patch, the script still gives me the following routes:
Unused routes (7): oauth/authorizations#show doorkeeper/tokens#create doorkeeper/tokens#revoke oauth/applications#edit oauth/applications#show doorkeeper/token_info#show omniauth_callbacks#(?-mix:(?!))
Here is a relevant code from doorkeeper on drawing these routes: https://github.com/doorkeeper-gem/doorkeeper/blob/5ea4575863781940fe6996692c6b41f2ad71d90e/lib/doorkeeper/rails/routes.rb#L25

## What are the relevant issue numbers?
