Hello!
In this code, the `SimpleFileType` instance passed as the first argument and the `"simple"` file extension as the second parameter.
As far as I can see in FileTypeManagerImpl:263:
```java
@Override
public void consume(@NotNull FileType fileType) {
register(fileType, parse(fileType.getDefaultExtension()));
}
```
There is no need to declare it explicitly as it is taken by calling `SimpleFileType.#getDefaultExtension()` by default, so this parameter is redundant.
To make tutorial more simple, I suggest this removal: seeing the second parameter is a bit confusing when we're passing the same value, returned from `getDefaultExtension()`.
Since the tutorial shows the basics, not a flexibility of an API, the parameter can be removed.
Thanks!
