PDQ Connect: Add Get Available Windows Updates scanner

[AndrewPla]

Marked No, working on a version that does for PDQ Connect in the scanner README.

Goal:

• Create a Connect-specific Connect-Get Available Windows Updates.ps1 script if the scanner can be made to work in PDQ Connect.
• If that is not possible, test the scanner in PDQ Connect, document the limitation, and close this issue with the result.

• Scanner README: README.md
• Main compatibility list: README.md
