Autofix broken Confluence links

[nwiltsie]

This PR replaces links to the old Confluence wiki in all plain-text files in this repository. I manually created a table of replacement links and used a regex to find and replace them - it's very possible something was mangled in that process, so whoever reviews this should confirm each of the replacement links.

Links work. PR template needs to be updated, but that's already listed as a separate issue.
