2022-02-08, Version 16.14.0 'Gallium' (LTS)

Notable changes:

Importing JSON modules now requires experimental import assertions
syntax

This release adds experimental support for the import assertions stage 3
proposal.

To keep Node.js ESM implementation as compatible as possible with the
HTML spec, import assertions are now required to import JSON modules
(still behind the `--experimental-json-modules` CLI flag):

```mjs
import info from './package.json' assert { type: 'json' };
```

Or use dynamic import:

```mjs
const info = await import('./package.json', {
  assert: { type: 'json' }
});
```
