To rough out the "multi deploy" idea:

• Set a target folder based on trigger type, like I do in the shinyapps deploy workflow.
• Use that to set the target-folder: variable for this with. Use PR-level folders for PRs, and then probably a dev (in addition to the root for main).
• We should also have an action to delete those PR folders when the PRs are closed, like I do with the shinyapps terminate workflow.
