Bumps Node requirements from 14 to 18 (#5445)

**What's the problem this PR addresses?**

We're still supporting Node 14, but it has reached end of life. Node 16
is still maintained, but will reach an early end of life in October, so
I think it's reasonable to drop it now rather than publish a major
release just for that.

**How did you fix it?**

Bumps the requirements from `14.16` to `18.12` (first LTS from the 18.x
release line).

 ### **Major Changes**
 
+- With Node.js 16's End of Life [approaching fast](https://nodejs.org/en/blog/announcements/nodejs16-eol), we dropped support for Node.js versions lower than 18.12.
 - Some important defaults have changed:
   - `yarn set version` will now skip generating the `yarnPath` configuration on new projects if it detects you're using [Corepack](https://nodejs.org/api/corepack.html).
   - `yarn init` will no longer use zero-install by default.
