Can we drop the revision_history.rst file in the docs?

[gvanrossum]

The docs have a purported revision history which is not very useful (it only marks major updates to the docs, not to actual mypy functionality) and a pain to maintain. Can we just drop it?

👍 -- maybe we can replace it with a link to the blog instead?

I am fine with dropping it. I am also fine with keeping it (it has some history about early days of mypy), but put a "tombstone" at the top, like this:

************************************
THIS FILE IS NOT MAINTAINED, SEE ...
************************************

@ilevkivskyi I mean it will remain in git history, so I don't see a problem with deleting it.

OK.
