make special paths it's own section for oauth and oidc actions

[russorat]

          It feels like this should have it's own section. I know there is **Special Paths** below, but it feels like this needs something more than just these two sections. I'm envisioning something where it's **How do I log users in?** and **How do I log users out?** and they are linked from here. Perhaps both of these are captured in a single section and can be linked as a "Learn more about login and logout"
