fix(cn): Fix translation error and align with the spacing conventions

[ChuYang-FE]

This PR focuses on:

• Fixing a translation error:
  The original English text:

  Now that roomId is not a reactive value (and can’t change on a re-render), it doesn’t need to be a dependency:`

  Correct translation:
  现在 roomId 不是响应式值（并且不会在重新渲染时改变），因此它不需要作为依赖项：

  I believe the previous translation "那它不就不是依赖" is a typo, and this PR corrects it.

• Unifying spacing rules:

  Added a space after English words to align with the spacing conventions across the document, ensuring consistency and better readability.
