Custom Javascript on Wiki pages

[upcc-jesse]

I would like to have a custom script run on each page. The goal of the script is to read the content of the page, identify certain keywords, and apply formatting to those keywords.

I've already written the script and tested it locally. Aside from editing the source code of the Wiki module, is there a way that I can add this script to each page globally? Something like the built-in Client Script DocType in Frappe, but for Wiki pages.
