Remove Node.js 16 from package.json engines field

Motivation:

This PR removes support for Node.js 16 to align with the React project's recent decision to drop Node.js 16 support (#28774). This change also prevents the following error from occurring when installing project dependencies with Yarn using Node.js 16:

error [email protected]: The engine "node" is incompatible with this module. Expected version "^18.18.0 || ^20.9.0 || >=21.1.0". Got "16.20.2"

Changes:

• package.json update: Removed the Node.js 16 version from the engines field in package.json, specifying only the supported Node.js versions (18.x, 20.x, 21.x):

"engines": {
  "node": "18.x || 20.x || 21.x"
},

How did you test this change?

• Dependency re-installation: Ran yarn install with Node.js versions 18.x, 20.x, and 21.x to re-install project dependencies and confirm that the previously mentioned error does not occur with these supported Node.js versions.
