endoscopy example doesn't work out of the box

The endoscopy example needs the endovis data, but this isn't referred to on the page, nor are there any instructions for downloading the correct data. We downloaded a sample set from a MONAI tutorial, and this gave us 9 jpg frames. When we started the MONAI label server, all 9 frames were loaded in slicer. I imagine this should have been just 1 file so that we could do the segmentation and then get the next frame.

More info on how to get the example running on the README would be beneficial.

内視鏡検査の例のREADMEから始め、Slicer内のMONAI Labelサーバーが想定するendovisデータを確認する。正しいデータのダウンロード先と、例の起動方法を文書化する。新しいユーザーが意図したデータを読み込み、セグメンテーションワークフローを進められるようになれば完了。
