Note

Low Risk
Documentation-only changes that mainly remove a deprecated configuration path; risk is limited to potential confusion if the new JS instructions are incorrect.

Overview
Updates the Osano privacy integration docs to use a custom JavaScript injection (osano.js) instead of configuring Osano via docs.json (integrations.osano.scriptSource), including new JS code samples and guidance for locating the Osano script URL.

Cleans up related privacy docs by simplifying the Osano card on the integrations overview and removing Osano’s docs.json schema entry from organize/settings.mdx, while keeping the cookie-consent-based telemetry disabling instructions (with clarified wording).
