[Internal] Fix Quality Monitor test by removing parallelism (#4568)

## Changes
<!-- Summary of your changes that are easy to understand -->
This PR removes parallelism in the quality monitor test. Currently, we
create multiple databricks_sql_table concurrently, which causes the
following error: `[OCC check failure] Entity proto at
/metastores:<metastore_id> may have been updated during the
transaction`.
This is already fixed in its non-plugin framework counterpart.
#4566
