radiant-mlhub-landcovernet example failing

The landcovernet example at https://github.com/microsoft/PlanetaryComputerExamples/blob/main/tutorials/radiant-mlhub-landcovernet.ipynb is currently failing for me.

>>> collection_id = "ref_landcovernet_v1_labels"
>>> collection = client.get_collection(collection_id)

During handling of the above exception, another exception occurred:

cc @KennSmithDS. Do you know if that collection ID was deliberately removed? Is there a good alternative?

打开 tutorials/radiant-mlhub-landcovernet.ipynb，并重新运行将 collection_id 设置为 ref_landcovernet_v1_labels 且调用 client.get_collection 的单元格。检查该 collection 是否仍然存在，以及示例是否指出了可用的替代项。collection 查找成功且 notebook 不再在此步骤失败，即表示完成。
