It seems that the URL of the POD links in the wiki could still be made to work. The scripts just need to be set up to place the generated POD files in the correct location on webwork.maa.org.
I don't know of any github workflow tools for POD generation, and am not familiar with github workflow tools in general. Are you referring to github actions? I did a little Google searching, and can't find anything specifically for perl pod generation and deployment.
I could probably help to write scripts that could deal with this, when I have time.
In the mean time, it seems like we could just copy the files from the current location to the correct place on the webwork.maa.org server to make them work.
