DESCRIBE YOUR PR

Tell us what you're changing and why. If your PR resolves an issue, please link it so it closes automatically.
The issue DOCS-B3C reported TypeError: NetworkError when attempting to fetch resource. (insights.algolia.io). This error occurs when Firefox's Enhanced Tracking Protection (ETP) or similar ad-blockers block the Algolia Insights SDK's click-tracking requests to insights.algolia.io. This is expected browser privacy behavior and not an application bug. Since the error is handled and harmless, it primarily creates noise in Sentry.

This PR adds a regex to the ignoreErrors array in src/instrumentation-client.ts to filter out these specific NetworkError events originating from insights.algolia.io. This prevents unnecessary error reporting to Sentry without affecting the functionality of the Algolia integration.
