Deploy sql-plugin-api artifact in DBR CI pipelines [skip ci] (#9195)

Fixes #9194

Addendum to #9148 that forgot to add a manual deploy

Testing:
```bash
$ BASE_SPARK_VERSION_TO_INSTALL_DATABRICKS_JARS=3.3.0 URM_URL=file:/tmp/m2-local ./jenkins/databricks/deploy.sh 

$ find /tmp/m2-local-local/ -name \*jar -ls
