Remove support for pytype (#176)

Also improve the generated package descriptions:

* List type checkers using a markdown list.
* Link the type checkers in that list.
* Instead remove the mention of specific type checkers from the
  introduction. (This removes mentions of pyre and PyCharm,
  but I assume that at some point we will add pyrefly to the supported
  type checkers anyway.)
* Use "type checkers" instead of "type-checking tools".
