Facilitate PR review with showing a diff between spreadsheet.

[sabrinatoro]

Issue coming from Nico-Sabrina 1:1 of March 13, 2024.

Currently, changes in the ontology are made in the source of truth google spreadsheet, used as components to the ontology.
We update the google spreadsheet, update the components, and the Diff seen in the PR should the change in the component tsv, which is often difficult to review.

Nico showed the "daff" command in ODK, which shows the diff between spreadsheets.
We would want to implement with command in VBO, so that we can more easily review PRs and see changes that we made in the source of truth spreadsheet.
