fix: 修复 README 中失效的 Star History 图表

[Dessalines39394]

当前 README 中的 Star History 图表已无法正常展示，原因是 GitHub stargazer API 的限制导致原服务失效。该项目需要恢复可用的 Star History 图表，因此将图表链接切换至无需 API token 的替代服务，并已在多个大型开源项目（如 JavaGuide、dify）中得到验证。

改动内容：

• 更新 README.md 与 README_EN.md 中的 Star History 图表链接及图片地址

Summary by CodeRabbit

• Documentation
  • Updated the Star History widget to use the new star-history.dera.page service.
  • Improved embedded chart URLs with SVG output and standard repository paths.
