Paimon version

Compute Engine
Engine-agnostic (core)

Minimal reproduce step

1. Open the "Supported FileSystems" table in docs/docs/maintenance/filesystems.mdx (lines 41-50).
2. grep -rn "dls" docs/ returns no match.
3. JindoDLSLoader.getScheme() (paimon-filesystems/paimon-jindodls/.../JindoDLSLoader.java line 39) returns "dls", and the class is registered in META-INF/services/org.apache.paimon.fs.FileIOLoader.
4. paimon-jindodls 1.4.1 / 1.4.2 are published on Maven Central.

What doesn't meet your expectations?
dls:// resolves to JindoFileIO at runtime (DLSFileIOTest#testDLSFileIO), but the docs state neither that dls:// is supported nor what it needs: the paimon-jindodls and paimon-jindo jars plus a Jindo SDK supplied by the environment — the model the OSS section of that page already describes.

Anything else?
Added in #7145, moved into paimon-jindodls in #7263; neither PR touched docs/.
