Improve Documentation for withFileParameter in Jenkins Pipeline

[josnin]

Describe your use-case which is not covered by existing documentation.

I encountered a scenario while using withFileParameter in a Jenkins Pipeline where the existing documentation did not provide sufficient guidance on how to handle and utilize the temporary file (*.tmp) effectively within the script. Specifically, I needed to process an uploaded file (FILE) and was unsure how to access and manipulate its contents due to its temporary nature

Reference any relevant documentation, other materials or issues/pull requests that can be used for inspiration.

Are you interested in contributing to the documentation?

Im interested, but I have limited availability due to other commitments.
