fix(ui): new animation build + additionalBrowserArgs (#823)

Description
---

- added new webgl animation build:
  - updated `three` to `r169` and replaced a deprecated function
- has the BG colour changes baked into the build so could remove it from
our index.html
- added `additionalBrowserArgs` with `ignore-gpu-blocklist` enabled and
`disable-accelerated-2d-canvas` disabled to hopefully prevent the WEBGL
context errors we've been getting

Motivation and Context
---
- trying to bring down the amount of WebGl errors (lots to be seen on
sentry)

What process can a PR reviewer use to test or verify this change?
---
- if you had been getting the `"THREE.WebGLRenderer: Error creating
WebGL context."` console error previously, you (hopefully:D) shouldn't
see it now
- if you can't run this locally to check then if we can find your
machine on sentry relating to that error + confirm it doesn't come up
any longer
