Display tool usage information when calling detailed help with 'ide help <tool>'

[slskiba]

A tool's command line help should be displayed when calling detailed help with ide help <tool> (and the tool is already installed for the project), to provide the user with usage information specific to the tool.

For example, for docker, currently the detailed help that has been added in #389, provides the following output: (detailed help is yet to written, "TODO docker" serves as a placeholder)

ide> help docker
__       ___ ___  ___
\ \     |_ _|   \| __|__ _ ____ _
 > >     | || |) | _|/ _` (_-< || |
/_/ ___ |___|___/|___\__,_/__/\_, |
   |___|                       |__/

Current version of IDE is SNAPSHOT
Usage: ide [option]* docker [<args>*]
