    [SPARK-57768][K8S][R][DOC] Fix R version comment to 4.5.2 in R Dockerfile
    
    ### What changes were proposed in this pull request?
    
    This PR updates the R version comment in the Kubernetes R binding `Dockerfile` from `4.1.2` to `4.5.2`, and removes the stale CRAN Debian link from the comment.
    
    ### Why are the changes needed?
    
    The base image (`eclipse-temurin:25-jre`) is now Ubuntu 26.04 LTS (resolute), whose default `r-base` is `4.5.2`. The `apt install` step already installs this version, but the comment still said `4.1.2`. The CRAN Debian link no longer matches how R is installed (from the Ubuntu archive), so it is removed.
    
    ### Does this PR introduce _any_ user-facing change?
    
    No.
    
    ### How was this patch tested?
    
    ```
    $ docker run --rm eclipse-temurin:25-jre bash -c '. /etc/os-release; echo "$VERSION_CODENAME"; apt-get update -qq; apt-cache policy r-base | grep Candidate'
    resolute
      Candidate: 4.5.2-1ubuntu2
    ```
    
    ### Was this patch authored or co-authored using generative AI tooling?
    
    Generated-by: Claude Opus 4.8
    
    Closes #56877 from dongjoon-hyun/SPARK-57768.
