Overview of changes:
Fixes #1862

Update CI scripts and documentation mention of the node.js version to 14

Anything you'd like to highlight / discuss:

• Will likely need a senior dev to update the netlify build script to use node.js 14 if not done already.
• I have this error when using node v14.15, which does not seem to work with the required packages after typescript migration. I think it is not critical as I am still able to run all the code normally, but wonder if we should specify this condition in our DG
  • 
• Any other places that I may have missed

Testing instructions:
I have been using nodejs v14 for quite a while locally and doesn't seem to have any issues, but feel free to test it if possible.

Thanks @tlylt

Seems fine to me as well. Maybe can get @ryoarmanda to double check on this?

Will need @ang-zeyu's assistance on this :)

Looks like the error might be resolved if your local node version is upgraded to a higher v14 version. As noted in the image, the packages support Node v14 among other versions (they also keep support for Node v12 too), but with a lower bound of 14.17.0. Your local node version is 14.15.1, which is below that. You can try upgrading it to a higher v14 version if need be, or jump to v16 LTS if you'd like.

Notwithstanding the above, I think the move to v14 should be done as v12 has reached end of life on 30 April.

I see. Do you think it will be good to mention in our DG that we require 14.17.0 and above? Currently, it will only say v14 and above, which is slightly misleading. (I assume that this is fine for end-users as long as they have v14 so need no specify for UG)

Yeah, let's do that 👍

LGTM 👍

I'll leave the merging to @ang-zeyu once the netlify build script has been updated :)
