Node version 16 breaks GitHub workflows

[GuentherJulian]

It seems that some of the dependencies used by the tutorial compiler are not compatible with Node version 16.
See for example: https://github.com/devonfw-tutorials/tutorial-compiler/runs/5181051825?check_suite_focus=true

This caused PRs in the tutorials repository to not upload to katacoda-scenarios-dev. After downgrading to Node version 14, the pipeline ran through.

A quick solution would be to use Node version 14 (or 12) in all GitHub actions where the tutorial compiler is used. In some of them there is already a fixed version Node 12 used.

https://github.com/devonfw-tutorials/tutorial-compiler/blob/main/.github/workflows/windowsMain.yml
https://github.com/devonfw-tutorials/tutorial-compiler/blob/main/.github/workflows/windowsPullRequest.yml

A better solution would be to update the dependencies in the tutorial-compiler so that it is compatible with Node 16.
