Add Management Portal "favorite" for Git WebUI

[isc-tleavitt]

For healthcare interoperability users, it's a bit unnatural needing to go into some specific class to get to the Git Web UI. Instead, it could be added automatically (?) as a favorite for all users - see https://community.intersystems.com/post/menu-management-portal

e.g.:

d ##class(%SYS.Portal.Users).%AddFavorite("Git: TRAINING","/isc/studio/usertemplates/gitsourcecontrol/webuidriver.csp/TRAINING//")

Note: to work properly with modern, this needs one of the following:

• SameSite=Lax session cookie setting on /isc/studio/usertemplates
• A session established first through a Zen popup in an (e.g.) interoperability editor
• GroupById set to %iscmgtportal on /isc/studio/usertemplates

The latter is the best option and should be included in the automation.
