When running through the steps on this page, if a user runs "Installation steps" istio#1, and then continues to Option 4 when using Helm 2.10.0 or later, an error is encountered due to the Istio CRDs already being installed (see istio/istio#10588), preventing the install from succeeding. Reordering the recommended production install method link will help prevent users from running into this issue, as they will not have already run step istio#1 before clicking on the link to https://istio.io/docs/setup/kubernetes/helm-install/

Change istio#1: OSX (bsd) sed requires an argument for -i
Change istio#2: OSX (bsd) xargs doesn't support -r, and it wasn't necessary to use anyway, so removed it

Before the Deployment was kept as minimal as possible. This is mostly
good, because users can set any Deployment settings and things work.
However, running as non-root is a bit quirky, and very very strongly
recommended, so I think its worth calling out here.

This is one of the istio#1 sources of confusion we get.
