BREAKING CHANGE:
Due to an improvement on how actions are defined, the enum `StarkSettingsActionsTypes`
became obsolete so it has been removed.

As a result, the following actions have been changed:
- `StarkPersistPreferredLanguage(public language: string)`
  -> `StarkSettingsActions.persistPreferredLanguage({ language: string })`
- `StarkPersistPreferredLanguageSuccess()`
  -> `StarkSettingsActions.persistPreferredLanguageSuccess()`
- `StarkPersistPreferredLanguageFailure(public error: any)`
  -> `StarkSettingsActions.persistPreferredLanguageFailure({ error: any })`
- `StarkSetPreferredLanguage(public language: string)`
  -> `StarkSettingsActions.setPreferredLanguage({ language: string })`

And also the previous union type has been replaced:
`StarkSettingsActions` -> `StarkSettingsActions.Types`.

Change in effect:

```typescript
// Before
@effect({ dispatch: false })
public starkSetPreferredLanguage$(): Observable<void> {
    return this.actions$.pipe(
        ofType<StarkSetPreferredLanguage>(StarkSettingsActionsTypes.SET_PREFERRED_LANGUAGE),
        map((action: StarkSetPreferredLanguage) => {
            // some logic
        })
    );
}

// After
public starkSetPreferredLanguage$ = createEffect(
    () => this.actions$.pipe(
        ofType(StarkSettingsActions.setPreferredLanguage),
        map((action) => {
            // some logic
        })
    ),
    { dispatch: false }
);
```

Change in `action` usage:

```typescript
// Before
this.store.dispatch(new StarkSetPreferredLanguage(language));

// After
this.store.dispatch(StarkSettingsActions.StarkSetPreferredLanguage({ language: language }));
```
