Add new subcommand "scoop diag"

[r15ch13]

Description

This introduces the new subcommand scoop diag.
It returns information about the Scoop environment using the Ini file format that can be posted on a GitHub issue (including markdown codeblock).
Sensitive content and the username gets automatically redacted.

Is there any other information that could be added to this (or redacted)?

Example output if run from inside Visual Studio Code `.\bin\scoop.ps1 diag`

Developer mode and other missing entries in scoop checkup should be added also, IMO.

Consider add it as a subcommand of scoop-checkup(scoop checkup diag), or a verbose/special output.(scoop checkup --verbose|diag...)

Remove the Markdown ini tag? If used in console, that's strange IMO.
