Viewport.d.ts using wrong imports

[mike-lischke]

The imports used in Viewport.d.ts cause eslint and VS Code to fail recognizing correct type information, which results in errors and failed code navigation. The current imports are:

import { Container, DestroyOptions, EventSystem, IHitArea, Point, PointData, Rectangle, Ticker } from 'pixi.js';
import { InputManager } from './InputManager';
import { PluginManager } from './PluginManager';
import { IAnimateOptions, IBounceOptions, IClampOptions, IClampZoomOptions, IDecelerateOptions, IDragOptions, IFollowOptions, IMouseEdgesOptions, IPinchOptions, ISnapOptions, ISnapZoomOptions, IWheelOptions } from './plugins/';

while they should be:

import { Container, DestroyOptions, EventSystem, IHitArea, Point, PointData, Rectangle, Ticker } from 'pixi.js';
import { InputManager } from './InputManager.js';
import { PluginManager } from './PluginManager.js';
import { IAnimateOptions, IBounceOptions, IClampOptions, IClampZoomOptions, IDecelerateOptions, IDragOptions, IFollowOptions, IMouseEdgesOptions, IPinchOptions, ISnapOptions, ISnapZoomOptions, IWheelOptions } from './plugins/index.js';

Note the mix of imports with and without .js extension. It is now recommended that imports should include the extension for new Node versions to find them.

In fact almost all imports are affected, including those in index.d.ts etc.
