Minor issues with images in 'Using dataset collections'

[AnnaSyme]

Some minor issues with images in GTN tutorial https://training.galaxyproject.org/training-material/topics/galaxy-interface/tutorials/collections/tutorial.html

Section "Calling Variants": written instructions show a single file as input; image shows the folder as input. (I think the image is correct? or it may not matter).

Section "Create a table of variants" has same issue.

Section "Collapse data into a single dataset": For "Where to add dataset name", the written instructions and image differ. (I think the image is incorrect.)
