  Update name of installation document (#446)

* Rename installation document

* Give better name to installation document.

Currently, there are three installation methods:
- via pip
- via zc.buildout
- via pipenv

This document was called "Install into a virtualenv" but a better name is "Install via pip", as all above mentioned ways to install Zope use a virtualenv.
