Collect topics and execution ideas for a 102 edition of the learning path

Multiple people have identified various opportunities to continue the learning path experience on various channels with more advanced topics (this repo, Slack, other repos, calls, ...).

This issue is to collect those references or ideas and to be able to use them later on to create said more advanced material.

Source and first idea:
https://github.com/InnerSourceCommons/InnerSourceLearningPath/pull/59/files/3dc60f7166de253aad59acf18f358ef9839ac98c#r267404860

从 issue 中的想法和参考资料开始，尤其是关于 pull request #59 的讨论。查看链接的评论和相关 learning-path 材料，以了解提议的高级主题；完成的标准是为未来的 102 版收集并整理可执行的参考资料。
