Modify the login unsuccessful/activation message

[mimo]

We have our forum account set to manual activation but it's not obvious to the user that is the case, so we get people trying to login right after and being given the generic login unsuccessful message. Which leads them to trying to reset their password or checking for an activation email etc. When in reality the account needs to be activated.

How can I change that error message to include something like "Your account may need to be activated my an admin, please contact them through Discord"?
