Sentry's sensitive headers are leaked when `sendDefaultPii` is set to `true`

Description

In version 10.11.0, a change to how the SDK collects request data in Node.js applications caused certain incoming HTTP headers to be added as trace span attributes. When sendDefaultPii: true was set, a few headers that were previously redacted - including Authorization and Cookie - were unintentionally allowed through.

• Affected version(s): >= 10.11.0, < 10.27.0
