Decide what to do with `@ai_track` decorator.

[antonpirker]

We have a decorator @ai_track which creates spans with an op either ai.run or ai.pipeline.

With the new AI insights module and agentic coding the concept of a AI pipeline is maybe not as important anymore?

We need to make a decision if we want to deprecated @ai_track or if we want to change it to make it work with the AI insights in Sentry.

The only documentation of the decorator I could find is this blog post: https://blog.sentry.io/ai-application-insights-with-sentry-llm-monitoring/
