devapp: add acme.ALPNProto to NextProtos

We need to add this manually in order to enable the tls-alpn-01
challenge, since we're using GetCertificate directly instead of
via Manager.TLSConfig. We also don't have the http-01 challenge
enabled (HTTPHandler isn't being used), so this is the only way
for a Let's Encrypt certificate to be acquired now that tls-sni-*
challenges have been deprecated.

In the future, this code can probably be simplified by using
higher-level APIs of autocert, but this fixes the immediate issue.

Updates golang/go#32272
