We used Dokuwiki in a similar situation. It's been a few years since I last used it (new client uses confluence) but I remember it was super easy to connect external tools. If your script can output text, Dokuwiki can display it :)

EDIT: I decided to try dokuwiki in Podman, works nicely as long as you run:
podman unshare chown 1000:1000 /path/to/wiki/data
I have a docuwiki running on RPi at home (files are stored on a USB-connected HDD) as a personal knowledge management system. It doesn't even need any DB, just stores it in text files. Took just a few minutes to set up. Doesn't get any simpler (other than using plain text files on local of course :)
Plus phenomenal pandoc support enables conversion from many formats to DokuWiki
I tend to abuse fossil for it's wiki. Mainly because it is zero fuss to setup.
I would have liked that too, except that I can't get oAuth integrated with fossil.
That would solve so many problems.
I cannot recall why i did not go for wiki.js myself, I tried, but I kept looking. Ended up with https://docmost.com/ and I've been quite happy. It's probably more equal to Notion then Wikipedia, but as a internal knowledge base it seem to be hit the right spot in terms simplicity and features.
I can't believe at this day, many products don't care about mobile viewing.
I thought it makes a big sense to write documents on PC and then view it elsewhere out there but developers don't seem to care about that usage.
Docmost makes tables completely unreadable on mobile having words wrap at the width of the device, especially when set as full-width which actually makes it even tighter for some odd reason.
Affine doesn't even support mobile at all and the GitHub issue about it is starting to age well.
AppFlowy does it the best of the bunch but it requires an app and it has minimal tablet support having only mobile app view than a native tablet view but at least it's usable having tables actually horizontally scroll as anyone would expect.
Outline isn't any better and a small test showed some weird behavior under mobile.
