[fix](docs) use metadata.source so "Edit this page" links to the real .md/.mdx file (#3648)

The previous logic in pathTransfer.ts rebuilt the source path from
location.pathname and unconditionally appended .md, so any .mdx file
(e.g. docs-next/connection-integration/mysql-proto.mdx) produced a
broken GitHub link. Use Docusaurus's metadata.source instead, which
always carries the correct file extension across all locales and
versioned docs.
