Added Search apt package command in Linux.md

This command helps to find the apt package if you don't remember the name of the package fully.

Can you pls provide an example, how one will be benefited from this command?

Yes, sure. For example, you want to install a package python-pyaudio but you don't remember the fully name of it. Before installation, you can use apt-cache search python-py . Then this command lists all apt packages containing the python-py keyword and you will see the full name of your package i.e. python-pyaudio in the list. You get the proper name and spelling of the package. Now you can install it using apt-get install package-name.
