[api-minor] Update the minimum supported Node.js version to 18

Browse source 
This patch updates the minimum supported environments as follows:
 - Node.js 18, which was released on 2022-04-19; see https://en.wikipedia.org/wiki/Node.js#Releases

Note also that Node.js 16 will soon reach EOL, and thus no longer receive any security updates.
