* move `policies_group.conf` to correct location
I originally assumed the file had to be placed into `scores.d`, but I
now know that `local.d` is actually correct.
* add configuration for composite symbols
See updates to #3690:
Additional Rspamd Symbols
Rspamd has so-called composite symbols that trigger when a condition
is met. Especially AUTH_NA and AUTH_NA_OR_FAIL will adjust the scores
of various lines in the table above. This needs to be taken into account.
* update CHANGELOG
