What's in this Pull Request?

To create reference to a SharePoint site or a SharePoint list, you'd create environment variables of Data source type:

• SharePoint site: Parameter type = Site, and choose a site from a drop down
• SharePoint list or library: Parameter type =List, and choose a list/library from a drop down.

The site reference is stored as URL, but the list references are stored as GUID.
In Power Automate, different actions reference SharePoint lists and libraries differently. Sometimes, it will be list Title, sometimes the URL (a.k.a. RootFolder), and other times, an Id.

The "Get Data Source List Info" flow retrieves SPO site and library information including their names, urls, Guids and driveIds.
