    Remove Docker VOLUME instruction for more flexibility

    Inheriting from the base image is made easier without
    the VOLUME instruction, since it cannot be reverted.
    All guides contain `--volume` explanations/usage
    examples anyway, so the VOLUME instructions in the
    Dockerfile aren't necessary.

    See also https://stackoverflow.com/a/62068396/11477374 for more
    examples for why that instruction can be harmful.

 ### Changed
 
+- Stopped mounting together the directories `/opt/adguardhome/conf` and
+  `/opt/adguardhome/work` in our Docker images ([#2589]).
 - When `dns.bogus_nxdomain` option is used, the server will now transform
   responses if there is at least one bogus address instead of all of them
   ([#2394]).  The new behavior is the same as in `dnsmasq`.
