* feat: adds an EnterpriseCatalogQuery.include_exec_ed_2u_courses field.
When True for an EnterpriseCatalogQuery record, this field indicates that
course content with type ``executive-education-2u`` should not be excluded from being associated with that record.
See related enterprise-catalog PR, which includes an ADR: https://github.com/openedx/enterprise-catalog/pull/507
