Given that we only use standard `import`/`export` statements now, after recent PRs, the "exports" global is unused. Instead we add "__non_webpack_import__" to the `globals` to avoid having to sprinkle disable statements throughout the code. Finally, the way that `globals` are defined has changed in ESLint and we should thus explicitly specify them as "readonly"; please find additional details at https://eslint.org/docs/latest/use/configure/language-options#specifying-globals
