Added "require" to exports for react-native-web imports to compile

[jkoutavas]

Description

Lovely package. I had to add this simple one-liner to it in order to use it from a React-Native-Web (RNW) application I'm working on. I probably would have gotten by with just using npx patch-package react-timezone-select but patch-package is ignoring my change to package.json

Linked Issues

Didn't create one, just went and requested this change.

Additional context

A bit of context, my vanilla RNW tsconfig.json file:

{
  "extends": "@react-native/typescript-config/tsconfig.json",
  "exclude": ["node_modules"],
  "compilerOptions": {
    "typeRoots": ["./src/types"],
    "isolatedModules": false,
    "allowImportingTsExtensions": false,
    "paths": {
      "react": ["./node_modules/@types/react"],
      "@shared/*": ["../shared/*"]
    },
    "lib": ["es6", "dom"] // ✅ Ensures TypeScript recognizes `document`
  }
}

If you need more context, let me know.
