docs: automatic secret detection for Python code variables

[ablaszkiewicz]

Documents the new code_variables_detect_secrets option in the Python SDK, which adds entropy-based detection of secret-looking values (API keys, tokens, strong passwords) in captured exception code variables — as a last resort after name-based masking.

Adds a concise Detecting secrets automatically section to the code variables / Python page covering: what it catches vs. ignores, that it's on by default, and how to disable it globally or per-context.

Pairs with PostHog/posthog-python#692.
