feat(insights): Adds create alert buttons to Total tokens used and Pipeline duration charts. Also fix bug with isForLlmMetric prop (#77031)

Adds create alert buttons to Total tokens used and Pipeline duration
charts.
Also fixes a bug with the `isForLlmMetric` prop not properly picking up
aggregates belonging to the LLM Monitoring alert category.

Didn't add an alert to the `Number of AI pipelines` chart yet, because
that chart uses `count()` on the spans dataset, but `count()` in
discover `metrics` points to the transactions dataset. Will update this
later.
