Before submitting your PR, there are a few things you can do to make sure it goes smoothly:- [x] Make sure to open an issue as a [feature request](https://togithub.com/googleapis/python-bigquery/issues/1512) before writing your code!  That way we can discuss the change, evaluate designs, and agree on the general idea- [x] Ensure the tests and linter pass- [x] Code coverage does not decrease (if any source code was changed)- [x] Appropriate docs were updated (if necessary)Fixes - [feature request](https://togithub.com/googleapis/python-bigquery/issues/1512)🦕- [internal bug](https://b.corp.google.com/issues/271044948)* chore(deps): update all dependencies (#1514)* chore(deps): update dependency charset-normalizer to v3.1.0 (#1518)* chore(main): release 3.7.0 (#1507)Co-authored-by: release-please[bot] <55107282+release-please[bot]@users.noreply.github.com>* feat: expose configuration property on CopyJob, ExtractJob, LoadJob, QueryJob (#1521)* feat: expose configuration property on CopyJob, ExtractJob, LoadJob, QueryJobNote for google-cloud-bigquery developers: This also refactors these classes sothat `_set_properties` does not modify the `_properties` dictionary in-place.Doing so was also mutating the request object, making it difficult to debugwhat request was _actually_ sent.
