Panic on "hugo serve"

[tksm]

What version of Hugo are you using (hugo version)?

$ hugo version
hugo v0.113.0+extended darwin/amd64 BuildDate=unknown

Does this issue reproduce with the latest release?

Yes (v0.113.0)

Description

Though I'm not sure if it's still supported, Hugo has an alias "serve" for "server".

$ hugo server --help | grep -A2 Aliases: 2>&1
Aliases:
  server, serve

But "hugo serve" has consistently failed with a panic since v0.113.0. It seems that the simplecobra does not support aliases.
