[FLUSS-2062][docs] Added Redirect for Latest Stable Version Docs

[rionmonster]

Purpose

Linked issue: close #2062

Per Issue #2062, this pull request adds redirect support for the latest stable version documentation (e.g. docs/0.8/engine-flink/getting-started/ → docs/engine-flink/getting-started/). This change will ensure that both implicit and explicit references to the latest stable version are resolved correctly, avoiding broken links.

Brief change log

• Added a dependency on the @docusaurus/plugin-client-redirects plugin to support performing client-side redirects.
• Added a new createRedirects redirect rule that applies only to the docs area, which will handle ensuring that the existing routes are evaluated and redirect routes are defined for those that are considered "unversioned" (e.g. "next", non-existant versions, etc.)
  • Note: The createRedirects function is not at all intuitive and I highly recommend reviewing over the documentation here to help make sense of things.

Tests

These changes were tested locally and require an explicit npm run build and npm run serve as redirect rules are only applied for production builds (so an npm run start will not apply them). You can see an example of this running locally and successfully navigating through the available versions and redirecting routes that explicitly use the latest, stable version (0.8) below:

Thanks folks! I just went and checked the site and it appears that things are working as expected (confirmed that https://fluss.apache.org/docs/0.8/engine-flink/delta-joins/#flink-version-support routes to the implicit https://fluss.apache.org/docs/engine-flink/delta-joins/#flink-version-support)!
