Update link to Record in docs

[agarwalrounak]

Summary
Record in docs, wherever mentioned, links to http://facebook.github.io/immutable-js/docs/#/Record/Record which then redirects to https://immutable-js.github.io/immutable-js/

However, the correct link for Record is https://immutable-js.github.io/immutable-js/docs/#/Record

@agarwalrounak Changes looks good to me. Thanks for your contribution 🎉

Draft.js uses immutable 3.7.x. We should link to the docs for that version, otherwise the'll be confusion.

Tuns out, there is no way to link to the older version of the docs. People have asked for old doc versions to be made available(here and here) but there seems to be no work towards that.

Hmm, I'd merge this PR if it linked to an old version of the docs through the Internet Archive. IMO it's the best option we have.

Draft.js uses immutable 3.7.4 which released on 18 Jun 2015 according to this commit immutable-js/immutable-js@09f04e9
I have linked Record to an old version of the docs(captured on 23 Jun 2015) through the Internet Archive.
