[Enhancement] Keep old version documents as they were

[Pil0tXia]

1. The Installation and deployment and SDK category should be in front of the Design documents category. (completed in https://github.com/apache/eventmesh-site/pull/152)

2. Older versions of the documentation should remain as they were in the Git repository at the time of each release.

@andream7 The sidebar sequence issue has been completed in https://github.com/apache/eventmesh-site/pull/152, however the old version docs still need help. Multiple versions are almost identical, and they do not align with the document structure and content in the Git repository. May you please help update?

Welcome any interested contributors to help resolve this issue.

You can download the documentation from the "site" repository on GitHub at the specific date corresponding to the release of the main repository.
