Hm, this is one people seem to have run across in the past but I can never seem to recreate it. It looks to be an issue for a lot of npm global installs across numerous modules. I've seen some people having success with this approach before gdotdesign/elm-github-install#21 (comment)

Essentially, create the directory it's failing to create, and chown it for yourself. Don't forget to rever it though.

Let me know if this works while I try to recreate this. I've honestly no idea what the issue is though, I'll keep trying to figure it out!

--unsafe-perms worked for me: https://github.com/nottoseethesun/Gridcoin-Tasks/blob/whitepaper-economics-update-and-edits/.github/workflows/build.yml#L17

--unsafe-perm did the trick for me too, here the actual command:
npm install -g mdpdf --unsafe-perm=true
