Changes description

This is a surgical fix to support a version of click which does not conflict with dbt-core 1.11.x. The principal difference between 8.1.8 and 8.2.0 is a change in exit code in certain places; the tests have all been updated to reflect this. I picked 8.2.0 rather than newer versions because the amount of rework needed for 8.3.x is significantly higher.
