Attribute indexing missing "sentry." prefix

### Environment

SaaS (https://sentry.io/)

### Steps to Reproduce

Traces view linking from attribute to query (ex: idle_span_finish_reason) does not function properly. Furthermore, group by dropdown is missing these attributes.

### Expected Result

When clicking on linking such as 'Find more samples with this value' it leads to a valid query. Group by should also have these attributes available.

### Actual Result

Invalid query/ results. Missing attributes in group by dropdown.
