Case-sensitivity in unit-test in column names failing after upgrading dbt-adapters from 1.16.6 to 1.16.7 (follow-up ticket)

[koletzilla]

Looks like there's a bug in the new dbt-adapters version that makes some column-names lower-case, breaking the compatibility with ClickHouse as CH uses case-sensitive column names ClickHouse/ClickHouse#33935.

Ticket in the dbt-adapters repository dbt-labs/dbt-adapters#1339

The test that we can use to detect this problem is dbt.tests.adapter.unit_testing.test_quoted_reserved_word_column_names::BaseUnitTestQuotedReservedWordColumnNames. We should add it back to the repo once this issue is fixed.
