chore(deps): bump imap-tools and python-gnupg

- imap-tools 1.15.0 -> 1.16.0 (1.15.1 fixes a ReDoS in the MailMessage.html parser; 1.16.0 fixes silent no-op mailbox actions with iterables and mixed ASCII/encoded-word address decoding)
- python-gnupg 0.5.6 -> 0.5.7

-: If you expose Paperless to the internet, set `PAPERLESS_URL` to its public URL
-or list its public hostname in `PAPERLESS_ALLOWED_HOSTS` to help protect against
-HTTP Host header attacks.
+: If you're planning on putting Paperless on the open internet, then
+you really should set this value to the domain name you're using.
+Failing to do so leaves you open to HTTP host header attacks.
 You can read more about this in [the Django project's documentation](https://docs.djangoproject.com/en/4.1/topics/security/#host-header-validation)
 
-    Separate multiple hostnames with commas, as in `example.com,www.example.com`.
+    Just remember that this is a comma-separated list, so
+    "example.com" is fine, as is "example.com,www.example.com", but
+    NOT " example.com" or "example.com,"
 
-    - With neither setting configured, Paperless accepts any host.
-    - With only `PAPERLESS_URL` set, Paperless accepts the hostname from that URL
-      and `localhost` (used by the Docker health check).
-    - `PAPERLESS_ALLOWED_HOSTS` adds hosts to `localhost` and the hostname from
-      `PAPERLESS_URL`, if set. A blank list adds no hosts.
-    - With `PAPERLESS_ALLOWED_HOSTS=*`, Paperless accepts any host, even when
-      `PAPERLESS_URL` is set.
+    Can also be set using PAPERLESS_URL (see above).
+
+    "localhost" is always allowed for docker healthcheck
+
+    Defaults to "\*", which is all hosts.
