Multiscales example fails to validate due to schema version mismatch

When I open the TCI example the geozarr validator throws a warning because the schema version is set to v1 and it expects it to be v0.1

```
/schema_url: must be equal to "https://raw.githubusercontent.com/zarr-conventions/multiscales/refs/tags/v0.1/schema.json", got "https://raw.githubusercontent.com/zarr-conventions/multiscales/refs/tags/v1/schema.json"
```

Inspect the TCI example's schema_url value and compare it with the URL required by the geozarr validator. Update the example to reference the v0.1 schema, then run the validator and confirm that the schema version warning is gone.
