cmd/doc: properly set GOPROXY to avoid deprecation checks

Browse source 
This change fixes a bug that was introduced in CL 675155. Instead of
doing the two step download and run with GOPROXY=off, do the run with
GOPROXY=<download cache>:$GOPROXY, so that we use the previously
downloaded version of pkgsite as the latest.

Fixes #73833
