Subject: [PATCH] Build: drop the retired sonatype-public-repository plugin
 repository

The nightly samples shard died in 2.8s, before a single test ran:

  Plugin org.apache.maven.plugins:maven-install-plugin:3.1.4 or one of its
  dependencies could not be resolved: Could not transfer artifact ...
  from/to sonatype-public-repository
  (https://ossrh-staging-api.central.sonatype.com/content/groups/public):
  status code: 400, reason phrase: Bad Request (400)

That endpoint is gone. Every path under the group now answers 400 with
"Endpoint /content/groups/public/... not supported. Please contact Central
Support" - the root, maven-metadata.xml and any artifact alike.

It was the only entry in <pluginRepositories>, so it was consulted ahead of
Central for every plugin the build resolves. The <repositories> block above
it already points ossrh at repo1.maven.org; the plugin repository was left
behind on the dead Nexus-style path. The OSSRH public group was a proxy of
Central plus staging snapshots, and snapshots were disabled here, so it
never served anything Central does not - removing it loses no coordinate.

Only one of the eight nightly shards failed because the other seven
restored a Maven cache that already held maven-install-plugin:3.1.4 and
never hit the network for it. Any shard whose cache misses a plugin fails,
so a pom.xml change that invalidates the cache key would have taken the
whole matrix down.

Verified with a full-reactor `mvn dependency:resolve-plugins` against an
empty local repository: BUILD SUCCESS, 551 artifacts downloaded, every
request to repo.maven.apache.org or repo1.maven.org and none to
ossrh-staging-api.
