* Passwordless SOGo auth: support for calendar invitations and calendar/contacts subscriptions

Inviting someone to a calendar event triggers a request to /SOGo/so/otheruser@example.com/freebusy.ifb/ajaxRead. Subscribing to someone's calendar/contacts triggers a request to /SOGo/so/otheruser@example.com/foldersSearch. The email address in the URL is different from the logged-in user, which needs to be handled appropriately by sogo-auth.php.

* Fall back to empty string if WATCHDOG_NOTIFY_EMAIL undefined (#4457)

By default, `.env` (`mailcow.conf`) does not define `WATCHDOG_NOTIFY_EMAIL`.

Using it in `docker-compose.yml` without having it defined leads to Compose v2 displaying this warning on startup:

> WARNING: The WATCHDOG_NOTIFY_EMAIL variable is not set. Defaulting to a blank string.

* increase opcache.interned_strings_buffer to 16 (#4487)

since version 23.0.2 Nextcloud recommends having a value greater than 8 for `opcache.interned_strings_buffer`. As this memory will be only used when needed this should have no impact on installations that are not using nextcloud.

* nextcloud - add missing redirections (#4366)

adds missing location directives to the nginx configuration of nextcloud 22, to prevent warnings in nextcloud admin center of missing redirections

* Update imapsync to 2.178 (#4491)

* Update and fix oletools (#4479)

As noticed by @MAGICCC (#4464 (comment)), our olefy image does not work anymore if you rebuild it. This is because @HeinleinSupport recently updated their repository with the changes from @decalage2's repository, which renamed olvba3 to olevba. Since @HeinleinSupport does not recommend using its own patched branch and is very slow in pulling in changes from upstream (@decalage2), let's switch to the latter. This also allowed me to revert #4464.

Finally, a minor patch to rspamd is necessary. While the documentation says

In the extended mode the oletools module will not trigger on specific categories, but will always set a threat string with all found flags when at least a macro was found.

This is not actually true -- it only sets it when suspicious or autoexec threats were detected. But it's a one-line patch to make rspamd behave as documented and we should submit that patch to @rspamd too. With this patch, I have confirmed that Mailcow will reject any incoming, non-whitelisted message containing attachments with macros.

This PR is updating SOGo to the new 5.5.0 Release (https://github.com/inverse-inc/sogo/releases/tag/SOGo-5.5.0) <-- Available in master.

It also includes the nsyslog Update to 3.28 (since the new SOGo builds are using a newer version), which fix a warning message inside the sogo container that the nsyslog version is outdated and can be upgraded to 3.28

This new release will have the Docker Image Tag: mailcow/sogo:1.106

This PR includes the Alpine Update 3.15 for the watchdog-mailcow container.

Fully tested (works flawlessly due to the fact that only the os got updated, not the script).

This PR will have the docker tag: mailcow/watchdog:1.96
