Help us improve the quality of our website documentation and code comments in English

As none of our current maintainers are native English speakers, it's inevitable that there are mistakes in our [website](https://www.kusionstack.io/) and code comments. To make sure that our users can clearly understand our work, we would greatly appreciate your help in improving the quality of our documentation.

- For code comments, you can submit pull requests to this repo directly.
- For website documentation, you can submit pull requests in the [website repo](https://github.com/KusionStack/kusionstack.io)

Review the repository's English code comments and the documentation on the linked website. For code comments, make focused pull requests to this repository; for website documentation, work in the linked KusionStack/kusionstack.io repository. Done means the selected text is clearer and the relevant pull request is ready for review.
