You are stuck on an old Bikeshed, because your CI is configured to use an old Ubuntu which only has Python 3.8. (Bikeshed bumped its minimum Python version to 3.9 some time ago. Unfortunately, I didn't realize this means that pip install bikeshed will just silently install the last 3.7-supporting Bikeshed version; had I realized this, I would have made an informative error message...)

The fix is to update your CI job's Ubuntu version to one that starts with Python 3.9 or higher; I recommend ubuntu-latest.

(Amusingly, I changed the format of the datafiles a while ago, which should have triggered this error in older versions a long time ago. But the CI that built the datafiles over in https://github.com/speced/bikeshed-data/ was also stuck on an old Ubuntu, and thus was stuck on an old Bikeshed, so it kept emitting the old datafile format. I fixed that last Monday, thus the current errors.)

Your fix works, but I am not sure if I follow. My Windows box has Python 3.9.2 and I still get the same error when running bikeshed.

Uninstalling and reinstalling bikeshed worked. pip would not upgrade bikeshed from 3.x to 4.x without that.
