Summary

Update the code base to move to using Object.hasOwn instead of Object.prototype.hasOwnProperty following the ESlint rule prefer-object-has-own and enforce this using ESLint.

This is currently pending because Object.hasOwn was not yet introduced in Node.js v14.18.0, which is still supported by this package.
