[IMP] tooling: makes 16.11 the minimum required Node.js version

Starting with Odoo 16.1, the ECMAScript version supported by Odoo has
been bumped to ES2022, but support for all ES2022 features has only been
achieved with Node.js 16.11*, making it the minimum required version to
run Odoo.

This commit updates the package.json to make this requirement explicit,
preventing from using the tooling with an outdated version of Node.js,
which would otherwise result in an unclear syntax error.

*: From all the features added in ES2022, support for static
initialization blocks is the latest to have been added, in Node.js
16.11, according to MDN's compatibility data.
