ci: Update tox

[sentrivana]

Description

Regenerating tox because we need to update the config for the langchain test suite in #5120 and I don't want to pull in lots of unrelated changes on the feature branch.

Dramatiq 2.0 has been released and our tests fail on it. Excluding it for now, we will follow up in #5123.

Issues

Reminders

• Add GH Issue ID & Linear ID (if applicable)
• PR title should use conventional commit style (feat:, fix:, ref:, meta:)
• For external contributors: CONTRIBUTING.md, Sentry SDK development docs, Discord community
