CI Improvements and fixes

• CI: fix Remark check (fix Remark CI complains about JavaScript syntax #1340)

[liushuyu]

The explanation for why this fixes Remark:

Node.js 12.x (LTS: Erbium) is an ancient version that does not support newer JavaScript/ECMAScript syntaxes. Upgrading to Node.js 16.x (LTS: Gallium) fixes the issue because it is a relatively new version that supports up to ECMAScript 2021.

Looks good to me, thank you for taking the time :)

I would prefer that these two commits be separated over two PR's. I am not sure about the 6gb ulimit change that's all dependant on the github CI infrastructure which we cant control. But the remark automation looks good.

That's true, however, GitHub uses Azure's facility, and Microsoft explicitly stated the VM SKU for GitHub Actions is Standard_DS2_v2. And here is the documentation: https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-runners-and-hardware-resources.
