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.

從內視鏡示例的 README 開始，確認 Slicer 中的 MONAI Label 伺服器所需的 endovis 資料。記錄正確資料的下載位置以及如何啟動示例；當新使用者能夠載入預期資料並繼續完成分割工作流程時，即視為完成。
