Summary

This PR adds an extra method to the DagsterGraphQL python client to enable the possibility to terminate multiple runs at the same time.

How I Tested These Changes

The PR contains a suit of unit tests similar to the other methods defined on the client, testing multiple edge cases for error handling.

Hi @baumann-t - thanks for sending this out. It looks like this needs a 'make ruff' and dagster-graphql-client query snapshot - can you run those and re-submit?

Hello @gibsondan! I've run make ruff and dagster-graphql-client query snapshot, let me know if this is ok with you now!

@baumann-t I realized one thing from looking at your query again - I don't think the TERMINATE_RUNS_JOB_MUTATION mutation is actually using the termationPolicy argument? you could either add it to the graphql query (being sure to re-run the snapshot command again) or remove it from the python

@gibsondan good catch thank you!.
I removed it for now to keep it consistent with the other function terminate_run. If we want to, we could add it to both as well
