[JENKINS-73798] Provide input as variable

[jenkins-infra-bot]

Using the "File Choice Parameter" I can provide a "Base Directory" and explanation tells: "This path will not be contained in choice list strings."
Fine so, but I need to use the provided value in the pipeline script.
So I ask for a parameter to reference this value.
