For some reason, GOPATH is being overridden in the `go mod download`
step after the latest machine image update in #15215.
This causes all of the modules to be downloaded to the
`/home/circleci/.go_workspace` cache instead of `/home/circleci/go` like
we require for the build (which will otherwise fail since we build with
`GOPROXY=off`).
Without this fix, the build will start to fail once the existing cache
is no longer used (after the root `go.mod`) is updated.
* Update mongodb atlas plugin version
