Bump Node.js environment to 18.x

- Bump Node.js to version 18. This change is necessary as Node.js v16
  will reach end-of-life on 2023-09-11. It also ensure compatibility
  with dependencies requiring minimum of Node.js v18, such as `vite`,
  `@vitejs`plugin-legacy` and `icon-gen`.
- Bump `setup-node` action to v4.
- Recommend using the `nvm` tool for managing Node.js versions in the
  documentation.
- Update documentation to point to code reference for required Node.js
  version. This removes duplication of information, and keeps the code
  as single source of truth for required Node.js version.
- Refactor code to adopt the `node:` protocol for Node API imports as
  per Node.js 18 standards. This change addresses ambiguities and aligns
  with Node.js best practices (nodejs/node#38343). Currently, there is
  no ESLint rule to enforce this protocol, as noted in
  import-js/eslint-plugin-import#2717.
- Replace `cross-fetch` dependency with the native Node.js fetch API
  introduced in Node.js 18. Adjust type casting for async iterable read
  streams to align with the latest Node.js APIs, based on discussions in
  DefinitelyTyped/DefinitelyTyped#65542.
