Revert "Merge branch 'doc-fix-db-gem-install-instructions' into 'master'"

This reverts commit 66d8ef1a, reversing
changes made to 6a8359f3.

The `--with` option was added in Bundler 1.10 but in this case it
shouldn't even be needed: I've tested the original command locally and
the pg gem was installed, so I believe the user that opened the original
MR ran the wrong command (i.e. `sudo -u git -H bundle install --without
development test postgres --deployment` instead of `sudo -u git -H bundle
install --without development test mysql --deployment`.
