Add sanitize() function, which wipes personal data and adds user URLs

[shaneh2]

This is a function for wiping sensitive data about Posit Connect users from the audit.connect::check() object.

Yet, we include URLs in the form of https://rsc.jumpingrivers.cloud/connect/#/people/users/<GUID>, so if you have access to the Posit Connect server, you can visit each of these links to identify users.

Example usage

CONNECT_API_TOKEN = 
CONNECT_SERVER_URL = "https://rsc.jumpingrivers.cloud/"

audit_connect_object = audit.connect::check(server = CONNECT_SERVER_URL,
					      token = CONNECT_API_TOKEN)

sanitized = audit_connect_object |> 
                audit.connect::sanitize()
sanitized$users_details$user_list$users

Then, sanitized$users_details$user_list$users doesn't contain any emails/usernames/first/last names. Instead, it contains a url column. This column contains a URL associated with each user.

Visiting one of these URLs will let you see details of the corresponding user, as well as administer their account.
