[x] Add important note that Ubuntu 20.04 uses dcmtk v3.6.4 which is compatible with openssl v1.1.0, but v1.1.1 is installed on Ubuntu 20.04 which breaks DICOM+TLS. Ubuntu 22.04 works just fine.
[x] General documentation fixes, trying to clean up the grammar a bit.
[x] Refer to /opt/mercure/tls/* instead of /opt/mercure/certs/* since keys are stored there in our example.
[x] Mentioned the /etc/environment variable that can be used to define the TLS environment variables. I'm not sure if you want to keep this one as there are lots of ways to specify environment variables.
