Fix view definition capture in DataHub for Vertica schemas with uppercase letters

[rohansun]

This PR fixes a bug where view definitions were not captured in DataHub when Vertica schema names contained uppercase letters. The table_schema column in V_CATALOG.VIEWS displays schema names exactly as they were created. For example, if a schema was created as CREATE SCHEMA myschema1;, it would be displayed as myschema1, while CREATE SCHEMA mySchema2; would be displayed as mySchema2, preserving the original casing.

The current code compares table_schema using table_schema = lower(any_schema_in_the_database), which causes issues with schema names that have uppercase letters.

This fix updates the query to use lower(table_schema) = lower(any_schema_in_the_database), allowing DataHub to capture view definitions for schemas regardless of whether their names contain uppercase characters.
