chore: fix samples pom.xml issues (#2660)

* Close dependency element for `storage_install_with_bom`
* Remove release please comment for storage control from `storage_install_without_bom`. Instead, allow renovate-bot to update when the version is available in maven central.
* remove duplicate declaration of `google-cloud-storage-control` in install-without-bom/pom.xml
