[Design][Discovery] Update the Wiki for contributing to the doc site

[babsdenney]

Description

We have this wiki linked on the 'Updating this site' page that is out-of-date. It would be great to get this wiki up-to-date and have it become a source for information on contributing to the doc site.

This ticket will probably be a little bit of discovery work and maintenance work to update it and also determine the next steps to make this wiki more helpful to people contributing to the doc site.
