pin webpack dependency versions so they won't break, and we can update them manually when we need to

[trusktr]

Note, this PR is superceded by

• [WIP] Convert to vanilla JavaScript modules (ES Modules) #183

which includes these changes. That PR removes build tooling, allowing the front end code to simply work forever without build tools breaking. This is advantageous because people here do not have the resources and time to fiddle with build tools.

Let end users configure build tools for their apps as they wish, while this repo focuses on the Sumerian functionality and the simplicity of maintaining it.

Description

We presumably had an in-range breaking change with a webpack dependency. I solved the issue by simply pinning webpack lib versions. I also update package-lock.json to ensure there's a way to reproduce a good build (f.e. with npm ci instead of npm install).

Related Issue #

This issue was noticed in

• Fixed issue #174 #175

but actually is not related to that change, and happens on mainline2.0.

Reviewer Testing Instructions

Run npm install && npm start and it should work.

Submission Checklist

I confirm that I have...

• removed hard-coded Cognito IDs
• manually smoke-tested the BabylonJS integration tests
• manually smoke-tested the BabylonJS demos
• manually smoke-tested the Three.js integration tests
• manually smoke-tested the Three.js demo

Additional (not part of the pull request template):

• manually smoke-tested the core integration test, but it is broken (including in mainline2.0), although not a big deal if both Babylon and Three.js demos work.
