Add ytdl-sub-gui template

[jmbannon]

This template adds ytdl-sub's new GUI image to unraid:

Nice app, sure beats my janky Bash script running on a cron job.

Thanks! You should give it a spin on unraid and let me know how it goes (including the template) - I actually don't use unraid so feedback here would be great

can we keep the same defaults for /media to aline with non gui version please? also encourage same unraid forum default.
I don't see a temp directory either.

#437 updates the old (headless) template with similar values in the gui version. Configs/subscriptions will use those new paths by default (/tv_shows, etc`) but we have to keep media for backwards compatibility

Confusing, not needed, and not best practice. But OK.
