Browser usage via script tag?

[TomiTakussaari]

Currently readme says about using this library via script tag in browser:

The Contentful Management library will be accessible via the contentfulManagement global variable.

However, it seems to me that after upgrading to webpack5, this has not been true, presumably because webpack output option "library" was removed.

If this usage is no longer supposed to be supported, Readme should probably be updated.

But, personally I like that this approach works, as it makes testing things a bit easier, so it would be cool if this approach could work in future too.
