fix(executor): Pass job object to get_snakefile when formatting CLI args

- `snakemake_executor_plugin_googlebatch/executor.py`: Modified the call to `self.get_snakefile()` within `GoogleBatchExecutor.run_job` to pass the `job` object as an argument.
- This change ensures that the `get_snakefile` method receives the necessary `job` context to correctly determine and format the `--snakefile` CLI argument for the Snakemake command executed on Google Batch, addressing a previously missing argument.
