Reuse the same threshold -> label -> count workflow on a Sentinel-2 water-index image to count Greenland supraglacial melt ponds, mirroring the cross-discipline 'Choose Your Own Adventure' pattern of the object-tracking-using-cell-profiler and process-image-bioimageio tutorials. Adds the CYOA Bioimaging/Earth split, the EO dataset (Zenodo 10.5281/zenodo.20960690), two EO result figures, the Earth observation tag, and OSCARS funding. Validated end-to-end on usegalaxy.eu (13 major melt lakes).

| > The image is a single-band ice-adapted normalised-difference water index, NDWI<sub>ice</sub> = (blue − red)/(blue + red) (Williamson et al. 2018, [doi:10.5194/tc-12-3045-2018](https://doi.org/10.5194/tc-12-3045-2018)), computed from a Sentinel-2 Level-2A scene (tile T22WEV, 2019-07-23) over the south-west Greenland ablation zone and rescaled to 16-bit so that melt ponds are bright. The preprocessing notebooks, the full Galaxy run provenance, the validation against an independently published lake map, and a citable archive are in the [OSCARS-FIESTA example repository](https://github.com/annefou/fiesta-galaxy-meltponds-eo). |

Add Earth Observation path to the introduction to imaging. I think it can help to promote the tutorials we created for image analysis and which contain Earth Observation Path.
