security/vaultwarden config.json.sample is not a JSON

Hi,

I noticed the change of config file location. It was previously in 
local/etc/rc.conf.d/vaultwarden (and I still have this file)
But according to this https://reviews.freebsd.org/D41602 new install 
location is local/www/data/config.json.sample so I looked in to this 
file and it is totally different than local/www/data/config.json. The 
later is real JSON file, but config.json.sample is not a JSON file at 
all so why it is named like it? (this is the source of the sample file 
https://cgit.freebsd.org/ports/tree/security/vaultwarden/files/vaultwarden_conf.in)

What is the right way to configure vaultwarden now?

Kind regards
