Update Babel version to support Class Properties

[Dimava]

When I'm trying to get https://unpkg.com/[email protected]/out/scope.js?module I'm getting an error:

Cannot generate module for [email protected]/out/scope.js

SyntaxError: unknown: Support for the experimental syntax 'classProperties' isn't currently enabled (11:16):

   9 | import { InternalTypeParser } from "./type.js";
  10 | export class InternalScope extends BaseScope {
> 11 |     parseCache = {};
     |                ^
  12 |     preparseAlias(k, v) {
  13 |         const firstParamIndex = k.indexOf("<");
  14 |         if (firstParamIndex === -1)

Add @babel/plugin-proposal-class-properties (https://git.io/vb4SL) to the 'plugins' section of your Babel config to enable transformation.

https://caniuse.com/mdn-javascript_classes_public_class_fields is supported in all browsers for quite a while

Please update Babel and other dep versions to fix this
