chore(llmobs): bump default dne API call timeouts to 10s (#14656)

## Description

bump default timeout for API calls in the DnE SDK from 5s to 10s, due to
reports of people still running into timeouts occasionally on small
datasets that uses the batch update endpoint

## Testing

unable to reproduce cases with 5s personally, but there is no
significant harm in bumping the timeout to 10s

## Risks

none, backend will handle the load with autoscaling if necessary
