John Spray 4049d2b7e1 scrubber: fix spurious "Missed some shards" errors (#8661)
## Problem

The storage scrubber was reporting warnings for lots of timelines like:
```
WARN Missed some shards at count ShardCount(0) tenant_id=25eb7a83d9a2f90ac0b765b6ca84cf4c
```

These were spurious: these tenants are fine. There was a bug in
accumulating the ShardIndex for each tenant, whereby multiple timelines
would lead us to add the same ShardIndex more than one.

Closes: #8646 

## Summary of changes

- Accumulate ShardIndex in a BTreeSet instead of a Vec
- Extend the test to reproduce the issue
