Caddy webserver support

[LecrisUT]

Can you include documentation for Caddy as a webserver? Here is the Caddyfile I am using which works perfectly well.

## Caddyfile
snipe-it {
   root * /var/www/snipe-it/public
   encode gzip zstd
   file_server
   php_fastcgi unix//run/php-fpm/www.sock
#   php_fastcgi localhost:9000
}

Is this issue still relevant?

[LecrisUT]

Sorry for the late reply, I have reformulated the issue to be more relevant for the caddy webserver issue only.

@jerm if you can take a look at this, vet the general approach, and then ping @snipe she can get the docs updated.
