Generate nice help text

[pionl]

Generate help text when calling ws --help.

• first render flows
• then show actions
• then show "internal" commands

Something like this:

• description could be gray
• ignore "default"
• tries to align the "description" in same line
• tries generate runs by returning "targets". Append to existing text.
• if createTargets is used nothing is generated in runs text
• XX if name is not set, use directory name.

Welcome to wrkflow workspace CLI for XX project. 

Usage:

ws ................ Runs default tasks in your config (change this description `workspace.flows.default.options.description = 'XX')`.
ws install ...... Setup the current workspace with the install command. Great for new users. 
ws check ...... Runs npm:format, npm:lint
ws npm:format .... Runs npm script.

If the we are in directory without workspace config and no "action" show different help text:

Welcome to wrkflow workspace CLI. 

Usage:
ws install <git-repository-url> ..... Install existing workspace from given repository.
ws init ........................................... Initialize new workspace in current directory

ws w:def ....................................... Copies current Typescript definitions to your project
