Azure-devops-docs: Please describe the workspace -> clean values

[spbrogan]

Anytime their is a set of valid values for a field can they be briefly described. Specifically my ask is for the workspace clean options.

workspace:
clean: outputs | resources | all # what to clean up after the job runs

We totally need this documented.

@TingluoHuang it wasn't obvious to me (from reading the code) how the workspace clean options get mapped to the agent, or what each one does. Can you share, and then @steved0x can fix up the doc? The options are "outputs", "resources", and "all".

[TingluoHuang]

resources: delete $(Build.SourcesDirectory) => _work1s
outputs: delete $(Build.BinariesDirectory) => _work1b
all: delete $(agent.builddirectory) => _work1
