Caddy falls over when encountering a softlink

[CHTJonas]

Caddy seems to trip up when serving a directory listing (in file browser mode) for a subdirectory when that subdirectory contains a softlink. Commands to reproduce below, but do let me know if you need anything else. Thanks for all your hard work!

$ caddy version
v2.4.6 h1:HGkGICFGvyrodcqOOclHKfvJC0qTU7vny/7FhYp9hNw=

$ uname -srvmo
Linux 5.4.0-1050-raspi #56-Ubuntu SMP PREEMPT Thu Jan 13 13:09:35 UTC 2022 aarch64 GNU/Linux

mkdir -p caddy-bug/test && cd caddy-bug
caddy file-server --listen 127.0.0.1:4523 --browse &
echo 'This is a file.' > test/file
curl -I http://127.0.0.1:4523/test/ # HTTP 200
ln test/file test/file-hardlink
curl -I http://127.0.0.1:4523/test/ # HTTP 200
ln -s test/file test/file-softlink
curl -I http://127.0.0.1:4523/test/ # HTTP 404

Bug appears to be present on Linux as well as macOS.

Please try with v2.5.0-beta.1, I think that's already been fixed.

Whoops, yeah this is a dupe of #4411 - sorry. I did search issues, but forgot to delete is:open from the default filter!
