devproxy --help made --as-system-proxy and --install-cert look like opt-in switches, but both default to true. This change shows the boolean argument and the default in the help text, and links to the system proxy docs:

--as-system-proxy <true|false>   Register Dev Proxy as the system proxy (default: true). See https://go.devproxy.net?go=system-proxy
--install-cert <true|false>      Install and trust the root certificate (default: true)

Only the help text changes. Parsing is the same, so bare --as-system-proxy still means true.
