`sess` package progress

Describe the bug
Early adopter of sess here just adding to the data in case its useful! I have one or two projects for which sess installed from the VSCode popup prompt, and it worked perfectly, and others for which it didn't. Today, I tried to deliberately add sess using rv add (I use rv for project package management):

rv repositories active!

Environment (please complete the following information):

• VSCode Version: 1.122.1 (Universal)
• R Version: 4.5.1
• vscode-R version: 3.0.0-rc.0

Additional context
Good luck! I'm quite optimistic that the sess package is the solution we've all been waiting for

Start by reproducing the failure with sess::connect() and the reported rv add command, using the .vscode/arf launcher and the supplied VS Code settings. Compare the working and failing project environments, including the sess commit and connection-info warning. Done means sess connects successfully from the R terminal and the reported warning no longer occurs.
