Start verdaccio earlier and keep it alive longer (#8016)

* Start verdaccio earlier and keep it alive longer

Start the verdaccio server immediately when running publish-npm and keep it
alive until the first OTP is entered. Also, add a tip for how to access the
server from your browser. This makes it easier to verify that all packages will
be published correctly to NPM.

* Fix CI timeout from asking to quit verdaccio
