A description of the work

A scan of the guides.18f.gov domain using Siteimprove resulted in this list of misspellings. The work of this ticket is to review and correct these typos. This can be done by editing the files directly in GitHub. Ideally all corrections would be made on a single branch that can then be merged in one PR.
