nodejs: upgrade eslint to v10

Currently, the codebase is pinned to `eslint@8` because existing Node.js libraries rely on the legacy `.eslintrc.json` configuration format.

ESLint v10 introduced a required flat configuration format (`eslint.config.js`) by default, which causes formatting failures when run against libraries with legacy configurations.

We should upgrade to use ESLint v10.

Start by locating the Node.js libraries that rely on `.eslintrc.json` and the commands that run ESLint. Read ESLint v10's flat configuration requirements and determine the needed `eslint.config.js` coverage. Done means the codebase uses ESLint v10 without formatting failures in those libraries.
