Updated apt configuration instructions
Putting apt repository keys in /etc/apt/trusted.gpg.d/ is considered a security problem these days. For more details, see [debian wiki](https://wiki.debian.org/DebianRepository/UseThirdParty) on the topic and [this post](https://askubuntu.com/questions/1286545/what-commands-exactly-should-replace-the-deprecated-apt-key).
I updated configuration instructions for apt in documentation to use the `signed-by` directive. It is compatible with Ubuntu 16.04 and up.
Closes #15146.
