Description

On Windows, building the documentation website (npm run build in website/) fails the broken-links check. The remark-version-replace plugin does not substitute the $FLUSS_VERSION$ / $FLUSS_MAVEN_REPO_URL$ placeholders, so the Maven-JAR links in iceberg.md, lance.md and paimon.md resolve to a literal $FLUSS_MAVEN_REPO_URL$/... and Docusaurus reports ~24 broken links (onBrokenLinks: 'throw'), failing the build.

Root cause: getDocsVersionName() in website/src/plugins/remark-version-replace/index.js splits the file path on '/' only:

const parts = pathname.split('/');
const websiteIndex = parts.lastIndexOf('website');

On Windows vfile.path uses backslash separators (e.g. C:\...\website\docs\engine-flink\reads.md), so split('/') yields a single-element array, lastIndexOf('website') returns -1, the function returns '', and no replacements are applied.

Steps to reproduce

On Windows, in website/:

npm run clear && npm run build

→ build fails with ~24 broken links pointing to $FLUSS_MAVEN_REPO_URL$/....
