[Pkg-roundcube-maintainers] Bug#951194: roundcube-core: update should not change config file permissions

[Daniel]

Package: roundcube
Version: 1.3.10+dfsg.1-1~deb10u1
Severity: normal

Dear Maintainer,

After an `apt upgrade` which upgrade roundcube-core, the group of /etc/roundcube/config.inc.php 
has changed, set to www-data, which in my case broke roundcube (the php user handling roundcube
is not in this group)

I guess a post-upgrade script should not change any permission, especially on a config file.
