Summary:
Adding 2024.2.0.0-b20 to upgrade test builds.
Parameterize and add 2024.2.0.0 to the basic upgrade tests.

- Ignore `builds.xml` file from linter
- Improve the test to handle transient failures when `allow_errors` flag is reset in the middle of a statement.
- Use a short statement timeout to prevent queries from getting stuck. This was occuring in mac release builds consistently.
- Removing output, and error string from upgrade_test_base `RunCommand` since this blocks if the output is too large.
