Rollup fails witn Node v16.6.0

[volovyks]

We should understand why this is happening and fix the bug or set supported versions of Node. Works fine with Node v16.14.2

set supported versions of Node sounds good for now

Hi 👋🏻 Do you have more details about this problem? Such as logs, or error messages?

[volovyks]

@Olyno not at the moment, but you can set node 16.6.0 with NVM and tests it.
I think we should follow Bo's advice and add the list of supported node versions to package.json.
Unit tests for all major node versions since v14 can be helpful. (But let's run build on 1 contract only + 1 test, because it will take forever otherwise).

I created a PR to specify the compatible Node versions as suggested. I got details about the Node 16.6.0 problem, available here: babel/babel#15015 (comment)
