Lower level for timeline cancellations during gc (#8626)

Timeline cancellation running in parallel with gc yields error log lines
like:

```
Gc failed 1 times, retrying in 2s: TimelineCancelled
```

They are completely harmless though and normal to occur. Therefore, only
print those messages at an info level. Still print them at all so that
we know what is going on if we focus on a single timeline.
