Improving the "Common Requirements" pattern

Some ideas for improving the Common Requirements pattern:

• Improve the Patlet - escpecially describe how the Solution is improving upon the Problem
• Break up Forces into bullets - so that readers can check more easily if these forces apply in their orgs as well
• Decide what to do with the Resulting Context: It currently focuses mostly on other related challenges that may need to be solved after this pattern is in place. However it lacks explanation of how this pattern has helped to address the problem i.e. how can people confirm "did it work"?
• improving the visual e.g. by creating a new version digitally (so no scan), and explaining in the pattern what that visual illustrates

To even level the pattern up to Validated, we would have to find 2 more Known Instances of orgs using this pattern. As this might be hard to do, it could be achieved in multiple steps (and PRs) over time.

先阅读 patterns/2-structured/common-requirements.md 以及 issue 中链接的 contributor handbook 章节，然后检查 assets/img/CommonReqtsv2.jpg。将工作分解为所列出的 pattern、视觉和验证改进；完成意味着所选更改已记录，并且该 pattern 包含所需的证据，如果要追求 Validated 状态，还包括另外两个 Known Instances。
