Examples: Revert usage of setAnimationLoop().

[Mugen87]

Related issue: #28296

Description

As suggested #28296 (comment) this PR reverts the usage of setAnimationLoop() in the examples to restore E2E testing.

[Mugen87]

Um, the E2E tests still fail (sometimes with very large diffs) 🤔 .

The only thing that is now different compared to last month is ci.yml which contains the migration task for the higher actions/upload-artifact version, see actions/upload-artifact#506.

Our change: 37e1cb5

Could it be worth pinging some of the people who work on the extensions at @actions to see if there's anything more obvious to them that might have changed?

Thanks for putting so much effort into fixing this, by the way 🙏

[Mugen87]

I have reverted the changes to ci.yml so we use actions/upload-artifact@v3 but still no luck. I also see many of those in the console:

JSHandle:THREE.WebGLRenderer: Error creating WebGL context., another attempt...

It seems there is a more fundamental issue with the workflow runner environment.

Closing. The root cause was not actions/upload-artifact and not setAnimationLoop() but macos-latest as the environment.
