fix: disable sentry profiling

What does this merge request do and why?

Error tracking is still enabled.

As mentioned here: https://gitlab.com/gitlab-org/modelops/applied-ml/code-suggestions/ai-assist/-/issues/1589#note_2839024058, we now see the segfault errors in the logs: https://cloudlogging.app.goo.gl/zWtbosNgBauYqjtP6

And the problem is that we have multiple profilers running simultaneously: Sentry Profiler and Google Cloud Profiler. The crash occurs because:

1. Multiple profilers are using Python's sys.setprofile() and threading.settrace()
2. Sentry's threading integration wraps threading.Thread.run()
3. When threads access typing internals simultaneously during profiling, we get memory corruption
4. The ThreadPoolExecutor workers are particularly vulnerable because they're created/destroyed frequently

We don't seem to use Sentry Profiling: https://docs.sentry.io/product/explore/profiling/. This is the Sentry page for the project: https://new-sentry.gitlab.net/organizations/gitlab/performance/?project=36. So let's go ahead and disable it according to https://docs.sentry.io/platforms/python/profiling/
