Add support for 3.12 in workflow files and configs.

[VersusFacit]

resolves #981

Problem

READ BEFORE REVIEWING

Adding Python 3.12 should pass a series of tests
✅ pytest tests/unit local
⏩ pytest tests/functional local (we do this with Dagger now)
⏩ dbt seed && dbt run in a local jaffle shop using plain pip install dbt-spark with 3.12 active covered by smoke testing run
✅ smoke testing run using test-bundle on snowflake against the jaffle-shop-base scenario with 3.12.3 active

• we'll need to add brew install unixodbc to Always Sunny for it to work with pyodbc 5.* which is needed for spark 🐢 ♾️

✅ GHA workflow involving integration tests (see below)
✅ release workflow still works (I'm not changing the 3.11 version here

Solution

We needed to update the pyodbc to get this working! It had no wheels for 3.12.

See this thread for one such documentation of this fact

No other changes beyond GHA workflows and setup.py are needed for this adapter.

release run to show steps working (except for audit obviously)

Temporarily set integration test parameter to 3.12 to show integration tests working.

Corroboration of smoke testing jaffle shop coming up clear.

[VersusFacit]

Before merge I'm going to revert the test version to 3.11 and open a ticket in smoke testing repo explaining what needs done to ensure we can use it with 3.12 on this adapter.
