[MOliverRoth]

What is the purpose of the change

This pull request adds a new documentation page that provides a practical guide for compiling multiple Flink releases on Windows, including older versions that require specific Java versions or build configurations.

Although Windows is not an officially supported build environment for Apache Flink, many contributors and researchers frequently attempt to compile legacy releases for analysis, debugging, or tooling purposes. This page provides guidance that reduces friction and clarifies the steps required to successfully build older versions on Windows.

Thanks for the feedback @davidradl !

I understand your points and I would like to addres both concerns:

I added the document on the chinese documentation so the PR becomes complete according to the documentation structure.

I'm also planning to prepare a version of this content for the Flink Wiki as you suggested, since this guide covers many releases. What do you think?

Thanks again for the guidance.
