docs: Fix file extension in FrankenPHP configuration

[francislavoie]

Corrected the file extension for additional configuration files in FrankenPHP section.

I could swear we have an open PR for this (the path is incorrect too).

[francislavoie]

Ah, 7b8cf6b only touched one but not the other

[henderkes]

#2059 seems like it missed an occurrence.

The path must be /etc/frankenphp/Caddyfile.d/*.caddyfile

[henderkes]

Hah, you were too fast. Thank you.

[dunglas]

.caddyfile or .Caddyfile? In Mercure we use .Caddyfile.

Line 19 in d200762

import Caddyfile.d/*.caddyfile

[henderkes]

I chose Caddyfile.d/*.caddyfile because that's what Caddy's copr and deb packages use. There's also some distribution that uses caddy.d/*.caddy though and I also saw *.Caddyfile.

It's a bit of a mess, like php's paths differing between apt, apk and dnf distributions. I therefore chose those based on a majority concept (i.e. conf.d instead of php.d because that's what apt + apk use) .

[francislavoie]

Caddy allows for Caddyfile* or *.caddyfile when used as the main config file, as per https://github.com/caddyserver/caddy/blob/6a4296b1a45d81f52bf8ab01d0bcaa4423fee3ff/cmd/main.go#L123. What's used for import doesn't really matter, but IMO .caddyfile is perfectly fine. Lowercase for extension is most sensible I think.
