[dependabot]

Bumps jsonpickle from 2.2.0 to 3.0.4.

Changelog

Sourced from jsonpickle's changelog.

v3.0.4

* Fixed an issue with django.SafeString and other classes inheriting from
  str having read-only attribute errors ([#478](https://github.com/jsonpickle/jsonpickle/issues/478)) (+481)
* The test suite was made compatible with `pytest-ruff>=0.3.0`. (+482)
* A `garden.yaml` file was added for use with the
  `garden <https://crates.io/crates/garden-tools>_` command runner. (+486)
* The test suite was updated to avoid deprecated SQLALchemy APIs.
* The `jaraco.packaging.sphinx` documentation dependency was removed.

v3.0.3

* Compatibilty with Pandas and Cython 3.0 was added. ([#460](https://github.com/jsonpickle/jsonpickle/issues/460)) (+477)
* Fixed a bug where pickling some built-in classes (e.g. zoneinfo) 
  could return a ``None`` module. ([#447](https://github.com/jsonpickle/jsonpickle/issues/447))
* Fixed a bug where unpickling a missing class would return a different object
  instead of ``None``. (+471)
* Fixed the handling of missing classes when setting ``on_missing`` to ``warn``
  or ``error``. (+471)
* The test suite was made compatible with Python 3.12.
* The tox configuration was updated to generate code coverage reports.
* The suite now uses ``ruff`` to validate python code.
* The documentation can now be built offline when ``rst.linker`` and
  ``jaraco.packaging.sphinx`` are not available.

v3.0.2

* Properly raise warning if a custom pickling handler returns None. ([#433](https://github.com/jsonpickle/jsonpickle/issues/433))
* Fix issue with serialization of certain sklearn objects breaking when
  the numpy handler was enabled. ([#431](https://github.com/jsonpickle/jsonpickle/issues/431)) (+434)
* Allow custom backends to not implement _encoder_options ([#436](https://github.com/jsonpickle/jsonpickle/issues/436)) (+446)
* Implement compatibility with pandas 2 (+446)
* Fix encoding/decoding of dictionary subclasses with referencing (+455)
* Fix depth tracking for list/dict referencing (+456)

v3.0.1

* Remove accidental pin of setuptools to versions below 59. This allows
  jsonpickle to build with CPython 3.11 and 3.12 alphas. ([#424](https://github.com/jsonpickle/jsonpickle/issues/424))
* Remove accidental dependency on pytz in pandas tests. (+421)
* Fix issue with decoding bson.bson.Int64 objects ([#422](https://github.com/jsonpickle/jsonpickle/issues/422))

v3.0.0

* Drop support for CPython<3.7. CPython 3.6 and below have reached EOL
  and no longer receive security updates. ([#375](https://github.com/jsonpickle/jsonpickle/issues/375))
* Add support for CPython 3.11. ([#395](https://github.com/jsonpickle/jsonpickle/issues/395)) (+396)
* Remove jsonlib and yajl backends (py2 only)
* Add ``include_properties`` option to the pickler. This should only
  be used if analyzing generated json outside of Python. ([#297](https://github.com/jsonpickle/jsonpickle/issues/297)) (+387)
