Provide a way to turn off Insights logging

Is your feature request related to a problem? Please describe 🙏

I recently integrated the InstantSearch SDK v7.26.1 and AlgoliaSearchClient SDK v8.19.0 in our iOS app in order to trigger several InstantSearch Insights events.

After I finished my integration debugging I was left with a verbose logging in my console that I cannot turn off. Every 30 seconds I get a log like this:

2024-03-06T14:37:01+0200 info Insights (B5UR3QDMCF) : [InstantSearchInsights] no pending event packages, skip flushing
2024-03-06T14:37:31+0200 info Insights (B5UR3QDMCF) : [InstantSearchInsights] no pending event packages, skip flushing
2024-03-06T14:38:01+0200 info Insights (B5UR3QDMCF) : [InstantSearchInsights] no pending event packages, skip flushing
2024-03-06T14:38:31+0200 info Insights (B5UR3QDMCF) : [InstantSearchInsights] no pending event packages, skip flushing
2024-03-06T14:39:01+0200 info Insights (B5UR3QDMCF) : [InstantSearchInsights] no pending event packages, skip flushing
2024-03-06T14:39:31+0200 info Insights (B5UR3QDMCF) : [InstantSearchInsights] no pending event packages, skip flushing

I instantiate Insights with:

    Insights.register(appId: ApplicationID(rawValue: algoliaAppId),
                     apiKey: APIKey(rawValue: algoliaApiKey),
                     userToken: UserToken(rawValue: String(user.id)))

I tried this, but it had no effect:

   Insights.shared(appId: ApplicationID(rawValue: algoliaAppId))?.isLoggingEnabled = false

This logging past the integration phase is unnecessary and pollutes the console, making it hard to see important logging.

Describe the solution you'd like 🤔*

Provide a way to turn of the logging, or better yet, make logging default to silent and only activate it when needed.
