chore: Update CODEOWNERS (#9853)

Cloud SQL samples ownership has moved from Cloud SDK back to Cloud SQL and as such the `infra-db-sdk` team should instead be `cloud-sql-connectors`

Will need someone to give write access to @GoogleCloudPlatform/cloud-sql-connectors on this repo for the CODEOWNERS file to be happy
