Change the default Maven Central URL in MavenUtils from repo1.maven.org to Google's Maven Central mirror for consistency with the SBT build (SPARK-55710). The DEFAULT_ARTIFACT_REPOSITORY environment variable can still override this. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Ur, @yaooqinn . Does this PR aim for Spark jobs to use Google Mirror even in the private data centers when --package is given?
Yes. The default repository URL for --packages resolution changes from Maven Central to its Google mirror. Users can override via DEFAULT_ARTIFACT_REPOSITORY.
#54508 affects only for the developers to build Spark, but this PR sounds dangerous to me. I'm negative for this.

Change the default Maven Central URL in
MavenUtils.scalafromrepo1.maven.orgto Google's Maven Central mirror (maven-central.storage-download.googleapis.com).Why are the changes needed?
Follow-up of SPARK-55710 / #54508 (suggested by @sarutak). The SBT build already uses the Google mirror as the primary resolver.
MavenUtilswas still defaulting torepo1.maven.orgfor runtime dependency resolution (e.g.,--packages). This makes it consistent.The
DEFAULT_ARTIFACT_REPOSITORYenvironment variable can still be used to override this.Does this PR introduce any user-facing change?
Yes. The default repository URL for
--packagesresolution changes from Maven Central to its Google mirror. Users can override viaDEFAULT_ARTIFACT_REPOSITORY.How was this patch tested?
Existing tests. The change is a URL swap for the same Maven Central content.
Was this patch authored or co-authored using generative AI tooling?
Yes, GitHub Copilot CLI was used.
