Add back support for node 16.10

[ParallelUniv3rse]

Feature Request

Description:
Please add back support for node 16.10 into the package.json engines field.
the latest versions of jest-extended cannot be used when you're trying to avoid high memory consumption by jest in node v 16.11+ as described in jestjs/jest#11956.

This concerns jest-extended ^2.1.0 as well as ^3.0.0.

Possible solution:
Lower engines requirements for node to 16.10 from 16.13 in package.json

[keeganwitt]

We officially only support actively maintained LTS releases. This is what is indicated by having 16.13 in engines; it was the first LTS release in the 16.x line. However, if for some reason you need to use a different version, you should be able to. The "unsupported engine" message is just a warning.

[ParallelUniv3rse]

Thank you for considering and for the explanation. Not sure about npm, but yarn fails to install on the engines requirement.

For anyone using yarn and looking for a workaround:
yarn install --ignore-engines

[keeganwitt]

Thanks for that comment. It's been a while since I've used Yarn and I forgot this behavior is different than npm. For npm, it just prints a warning, there's no ignore parameter needed, e.g.

$ npm i -D jest-extended
npm WARN notsup Unsupported engine for jest-extended@3.0.1: wanted: {"node":"^14.15.0 || ^16.13.0 || >=18.0.0"} (current: {"node":"14.10.1","npm":"6.14.8"})
npm WARN notsup Not compatible with your version of node/npm: jest-extended@3.0.1
...

It's worth noting, that a bunch of the latest Jest dependencies behave the same way,

I think we can do the same here as in jestjs/jest#12754 and kulshekhar/ts-jest#3495 just so people don't have to supply a flag (or ignore warnings).

[keeganwitt]

I don't object. I don't pay much attention to engines warnings personally.

Node 16 (and even Node 14) supports optional chaining, so you're not using that.

That said, this is not the correct issue (or even repository) to report your issue.
