Add case sensitive table name tests

Follow up to this PR: https://github.com/Azure/data-api-builder/pull/2473

The above PR is fixing the underlying issue reported here: https://github.com/Azure/data-api-builder/issues/2385

in order to correctly test that case sensitive table names are supported we need to generate our test DBs in a way that they support case sensitive collation for table names. More investigation is needed to determine how to do this in our pipeline, and then the tests for such table names must be added.
