Import `Enum` and create a sub-class that inherits from `str` and from `Enum`.

By inheriting from `str` the API docs will be able to know that the values must be of type `string` and will be able to render correctly.

Then create class attributes with fixed values, which will be the available valid values:

Если такого пользователя нет, то мы возвращаем ошибку "Incorrect username or password" (неверное имя пользователя или пароль).
