fix: Monitor for changes in supported letsencrypt locations (#2279)

Browse Source 
Previously we only monitored for `$HOSTNAME` in `/etc/letsencrypt/live` and only for hard-coded `.pem` filenames.

This ensures we check the locations of other locations that may not match `$HOSTNAME`, which we also support. Ideally in future at least the directory to look in would be better known in advance..
