Sonatype snapshots failing again

They were fixed in https://github.com/google/auto/issues/1832 back in October, but they started failing again in late June. Here are the last successful run and the first failing run. The first failure came after https://github.com/google/auto/pull/1933, but the failure at least naively seems unrelated to that:

Error: Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:3.1.2:deploy (default-deploy) on project auto-common: Failed to deploy artifacts: Could not transfer artifact com.google.auto:auto-common:pom:HEAD-20250701.023018-657 from/to sonatype-nexus-snapshots (https://oss.sonatype.org/content/repositories/snapshots/): status code: 403, reason phrase: Forbidden (403) -> [Help 1]

Granted, who knows, it could be that the new maven-invoker-plugin is trying to deploy itself when it shouldn't or something.
