    docs: list Java 25 in backend runtime requirement
    
    backend-setup.md said "Java 11/17/21", but since 10.4.0 the default
    (unsuffixed) OAP Docker image is built on eclipse-temurin:25-jre, and CI
    builds/tests on 11/17/21/25. Update the requirement to "Java 11, 17, 21,
    or 25" and note the default image tag is Java 25 alongside the published
    -java11/-java17/-java21 variants. Java 11 remains the compile target/minimum.

 ## Requirements and default settings
 
-Requirement: **Java 11/17/21**.
+Requirement: **Java 11, 17, 21, or 25**. The OAP is compiled for Java 11 (the minimum runtime), so the binary distribution runs on any of these. Official Docker images publish `-java11` / `-java17` / `-java21` tag variants; the default (unsuffixed) image tag is built on Java 25 (`eclipse-temurin:25-jre`).
 
 You should set up the database ready before starting the backend. We recommend to use BanyanDB.
