Support passing args as keyword argument for run-operation in programmatic invocations

[dbeatty10]

resolves #10355

Problem

As described in #10355, there's a naming conflict between the first parameter of dbtRunner.invoke() and the --args CLI flag of the run-operation command.

Solution

1. Make the first parameter positional-only
2. Rename the first parameter from args to invocation_args
3. Allow run_dbt and run_dbt_and_capture test utilities to take optional kwargs parameters for testing purposes
4. Update the small handful of places that were using a keyword parameter rather than positional

Interface changes

These interface changes assume that the intended and dominant usage of dbtRunner.invoke is a positional first argument along with optional kwargs:

• Within dbtRunner.invoke rename args to invocation_args and explicitly make it positional
• Align run_dbt and run_dbt_and_capture with those same changes

If anyone has code like dbtRunner().invoke(args=["run", ...]) they would need to update it by removing args=.

Testing strategy

Indirectly testing dbtRunner().invoke() via run_dbt_and_capture & run_dbt -- added this new test to verify that custom args makes it through:

    def test_args_as_keyword(self, project):
        results, log_output = run_dbt_and_capture(
            ["run-operation", "print_something"], args={"message": "Morning coffee"}
        )
        assert "Morning coffee" in log_output
