Better Installation Instruction

[ftrotter]

We would like to improve the installation instructions for HADES with container and Linux instructions.

Inspired by our Github Actions workflow, here are the Linux libraries you'll need:

apt-get install -y libssh-dev
apt-get install -y default-jdk         
apt-get install -y make                
apt-get install -y libicu-dev          
apt-get install -y libcurl4-openssl-dev
apt-get install -y libssl-dev          
apt-get install -y libxml2-dev         
apt-get install -y pandoc              
apt-get install -y git                 
apt-get install -y libssh2-1-dev       
apt-get install -y libpq-dev           
apt-get install -y unixodbc-dev 

I don't see libsodium, but some packages (like keyring) will need that too,
