fix: update index.d.ts

[oskCom]

Fix #85 #101

I referred to #94

[nornagon]

Confused why not update all of these?

Suggested change

	export var BrowserView: typeof Electron.BrowserView;
	export var BrowserWindow: typeof Electron.BrowserWindow;
	export var BrowserView: Main.BrowserView;
	export var BrowserWindow: Main.BrowserWindow;

etc.

Thank you for your review.

I tried.

export var BrowserWindow: Main.BrowserWindow;

However, an error occurs because the static member of BrowserWindow cannot be referenced.

code&error

import * as _remote from '@electron/remote';
_remote.BrowserWindow.getAllWindows();
                      ~~~~~~~~~~~~~~~
                      ^ Property 'getAllWindows' is a static member of type 'BrowserWindow'.
