Show parameter help in the parameter tooltips

[MartinGC94]

Prerequisites

• [X] I have written a descriptive issue title.
• [X] I have searched all issues to ensure it has not already been reported.

Summary

Similar to how the completion tooltip for commands include a summary of the command, it would be nice if the parameters also included the parameter help. So for ls -Path the tooltip would show:

[string[]]
Specifies a path to one or more locations. Wildcards are accepted. The default location is the current directory (`.`).
