various typo fixes and edits for 38 39 41

[N3llz]

• duplicate line in 38: These images were curated from a variety of sources by the Imaging Platform at the Broad Institute for the 2018 Data Science Bowl. Please contact the Imaging Platform.
• Add this line to 39: "A small fraction of the images in this dataset overlap with the BBBC038 collection, which is the Data Science Bowl 2018 dataset. Not all images in this dataset were included in the DSB 2018 challenge to avoid a dominant number of fluorescent images for the competition. The BBBC038 collection has more variety of experimental conditions, whereas this dataset comes from a single high-throughput experiment with a large number of perturbations."
