scripts: completion.pl: sort the completion file for all shells

The reproducible builds effort in Debian has caught a regression in curl
8.13.0-rc1 but we were a bit slow to realize it. The ordering of the
completion file for fish is not deterministic so it can differ between
builds. Since there is no restriction about the order of the completion
file for fish, let's just sort it too.

Closes #16985
