Bug description

Crashes with Error: Must use import to load ES Module:
@babel/runtime/helpers/esm/objectSpread2.js
require() of ES modules is not supported.
require() of @babel/runtime/helpers/esm/objectSpread2.js
from react-big-calendar/lib/Calendar.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename objectSpread2.js to end in .cjs, change the requiring code to use import()

Expected Behavior

Hey @wayimp, could you try testing the fix in #2157 by changing your package.json dependency to the following:

{
  "dependencies": {
    "react-big-calendar": "git+https://github.com/sangeeth96/react-big-calendar#fix/babel-dist-lib-no-esm--dist"
  }
}

and see if this fixes the issue?

I tried to test this like you asked, but my build still failed, and then I got distracted on another task. Thank you for releasing a fix so quickly. It's all good now.
