Add commandline output for licence about biosimulators_utils HOT 3 OPEN

This actually may not be necessary as the docker files will not contain any code that is GPL licensed themselves. We can keep the repository MIT licensed according to the following from the Linux Foundation

The license of dockerfiles vs. software inside containers
The Dockerfile files can be licensed under an open source license themselves. It is vital to realize that the scope of this license statement is only the Dockerfile and not the container image.

For example, the Dockerfile itself can be licensed under the MIT license but describing the installation of GPL licensed software. In a typical use case, the license of the Dockerfile and the license of the described software are entirely independent.

I think this is mainly an issue for the individual containers and their command-line interfaces. The template and documentation can simply state that command-line programs should state license terms as necessary.

I don't think this applies to our current simulators

• BioNetGen: MIT
• COPASI: Artistic-2.0
• tellurium: Apache-2.0
• VCell: MIT

This would apply to some of the other simulators we're targeting

• AMICI: BSD-3-Clause
• CBMPy: GPL-3.0-only
• CNORdt: GPL-2.0-only
• COBRApy: LGPL-2.0-or-later OR GPL-2.0-or-later
• GillesPy2: GPL-3.0-only
• iBioSim: Apache-2.0
• PySCeS: GPL-3.0-only

This could be incorporated into biosimulators_utils.simulator.cli.
