Fix misspellings, reword a few sentences in public documentation
requested to merge gonzalo-bulnes/reproducible-website:fix-misspellings-in-public-documentation into master
Overview
This merge request fixes a few misspellings in the public documentation. It also rewords a few sentences for clarity.
Notes
The misspelling fixes are straightforward. The choice of words can be more subjective, and for that reason I kept commits distinct hoping it would make review easier.
I found no CONTRIBUTING guidelines, so I did what made sense to me but I'm happy so edit/squash/remove commits if preferable.
