cli/supported_licenses: simplify the license list

[perillo]

Remove the license reference, since it may not fit the terminal.

Move the license name before the license id, in order to improve the user experience.

Make the text width dynamic, in order to improve readability.

• Added a change log entry in changelog.d/<directory>/.
• Added self to copyright blurb of touched files.
• Added self to AUTHORS.rst.
• Wrote tests.
• Documented my changes in docs/man/ or elsewhere.
• My changes do not contradict
  the current specification.
• I agree to license my contribution under the licenses indicated in the
  changed files.

I started to use REUSE and I noted that the supported_licenses command it not very user friendly.

Each lines are too long, and on sway + foot I'm unable to select the license URL.

So I decided to remove the license reference.

If you agree to this change, it should possible to add an option to show all the details of a single license, with all supported metadata like link, OSI approved and FSFLibre approved;
see https://github.com/spdx/license-list-data/blob/main/licenses.md as an examples.

It would be useful to add filters based on OSI and FSFLibre compliance.

Thanks.
