[ADAP-877] [Bug] Updating agate_helper in core requires update in of data type in some tests

[McKnight-42]

Is this a new bug in dbt-bigquery?

• I believe this is a new bug in dbt-bigquery
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

the core merger of dbt-labs/dbt-core#8561 causes failing tests in docs_generate due to adding an integer to the definition which requires us to swap from float to int for expected values.

Expected Behavior

updating the expected type allows tests to pass again.

Steps To Reproduce

update local branch to main and run functional tests to see failures corresponding to error around stat field not meeting expected type.the
