Python SDK

Description

From Sentry Feedback: DOCS-8ZK

this config not working in sentry-sdk[fastapi]==2.25.1

Suggested Solution

Underlying problem and proposed solution

The page referenced in the user feedback is not very descriptive about how the set_level function works. Since the default levels that the SDK sets will be reasonable for most use cases, this page is not useful for most users, and we the best course of action is likely to simply delete the page.
