fix: switch Maven Central publishing from OSSRH to Central Portal

Replace old s01.oss.sonatype.org OSSRH endpoints (402 Payment Required)
with central-publishing-maven-plugin v0.10.0 for the new Central Portal
(central.sonatype.com). Remove distributionManagement section and
nexus-staging-maven-plugin from release profile.
