Only download but not install Java

[tobiasdiez]

In order to use jpackage, one needs to download and extract the early access version of jdk 14. However, no installation is necessary. It would be nice if you could provide an option to download and extract java without installing it.

The download links for Java 14 can be found under: https://jdk.java.net/jpackage/

Would also be good to point to a URL instead of a JDK hosted in the Git repository. The JDK is not a small file and having it on Git is suboptimal. GitHub itself limits file size to 100MB, making it impossible to use this feature as designed.

Currently I can't use GitHub Actions for a use case that I can use with Azure Pipelines due to this limitation.

FYI, I released such a dedicated download-only action at https://github.com/marketplace/actions/download-jdk loading JDKs from https://jdk.java.net

@sormuras thank you for providing and supporting the separate action.
For now, we don't have plans to build in this functionality to this action so using https://github.com/marketplace/actions/download-jdk could be a good alternative
