[email protected] broke usage with Node.js v14 and earlier: #80 uses String.prototype.replaceAll, but this isn't supported in Node.js v14 (https://node.green/#ES2021-features--String-prototype-replaceAll).

The engines.node in package.json suggests that Node.js >=0.8 is supported:
https://github.com/pillarjs/finalhandler/blob/v2.1.0/package.json#L33-L35

Of course, ci.yml only tests with Node.js v18 and later.

For my usage, I'm totally if finalhandler v2 only supports Node.js v18 and later. If so, it would be helpful to update engines.node in package.json, or just remove it.

Thanks.
