fix(sdk): remove non-llm instrumentations to reduce noise

[nirga]

These can be manually added by users who wish to use them, but having them by default adds a lot of noise and un-needed spans for our users.

• [ ] I have added tests that cover my changes.
• [ ] If adding a new instrumentation or changing an existing one, I've added screenshots from some observability platform showing the change.
• [x] PR name follows conventional commits format: feat(instrumentation): ... or fix(instrumentation): ....
• [ ] (If applicable) I have updated the documentation accordingly.
