Prefix Hermes V1 version with hermes-v for Maven Central lookup

The Maven Central artifact version uses the hermes-v prefix (e.g.
hermes-v250829098.0.10), but the version.properties file stores
the raw version number. Add the prefix when constructing the
HERMES_VERSION env var so the prebuild script finds the artifact.
