[Feature]: Auto document cli in markdown

[olih]

Describe the problem

Usually, CLI program gets documented in markdown so potential users get an understanding of the available features.
This is usually a manual process, and often the code will change but the documentation will not be updated.

Describe the solution

New command for the cli baldrickdoc-ts cli
Auto generate the documentation for the CLI based on the --help
The easiest approach is just to capture the --help for each command and enclose it as fenced code.

The newly generated documentation can be then saved in new markdown file CLI.md

Additional context

Right now, we are using commander.js for the CLI, but this could change in the future.

Is this new feature a good fit ?

• Needed: an existing user is going to need this in the short term
• Specific: the problem is clearly understood and defined
• Small change: This new feature represents a reasonably small change
• Same scope: this new feature does not change significantly the scope of this project
• Long term maintenance: moving this to a new project would make long term maintenance harder
