Change the URLs in the installation instructions to new mirrors that are expected to provide faster downloads for users. This update affects the installation guides for both detectron2 and magic-pdf in the Chinese documentation.

A pre-release version0.6.2b1 of magic-pdf is now available. This version includes
many fixes addressed in our logs but has not undergone full QA testing. Users are
advised to report any issues encountered or revert to version 0.6.1. The installationguides in both Japanese and Chinese READMEs have been updated to reflect the availability
of this pre-release version and the previous stable version.

BREAKING CHANGE: Installation commands now point to version 0.6.2b1 by default.
Users who wish to install the stable version 0.6.1 should follow the provided
command instead.

- Emphasize the importance of mainline support for stability and reliability.
- Define the supported operating systems, CPU architectures, memory requirements,
  Python versions, Nvidia drivers, and CUDA environments.
- Provide guidance on GPU hardware support and minimum/recommended configurations.
- Include a note on compatibility issues and the importance of using the specified
  versions of dependencies.
- Update installation command and verify version to prevent incorrect package installations.
- Add missing GPU quick start guides for Ubuntu and Windows.
- Refactor usage example code by initializing an empty list for `model_list` and
  adding a call to `pipe.pipe_analyze()`.
