Trigger synchronisation of file system provider from Home Assistant

[DarkFox]

I've got a script that fetches the latest podcasts from a few feeds, and writes the url to a .m3u file for each feed, which are then are available as playlists in Music Assistant (config, for reference).

However, some of them update quite often (one of them hourly), so I'd like to be able to trigger a synchronisation from the script, so the latest podcast is always available.
