check line breaks added to "creation"

[njr2128]

<br> added to creation.md. After the next deployment, check to see if lines were added. May need to add two <br>s instead, as in tables on credits page.

If yes, consider adding additional line breaks to other edition-webpages, especially:

• edition
• sponsors
• about the manuscript
  but check others too

OR consider change to stylesheet - to add space after paragraph (ie line break)
