Reproducibility and source dataset alignment

[egrace479]

@SMRayeed, let's get the Citation and source dataset link fixes I made merged (please review), and you can open a new PR with the Todo:

• [TODO]: It is unclear how to reproduce the work done here due to alignment issues within the included metadata and notebooks, including references to files that don't seem to be publicly available (see issue Provenance of CanonBeetles.csv #4 & Alignment to Original Source datasets for Reproducibility #5 discussions). This needs to be resolved for reusability and reproducibility of this work.
