diff2html appears not to work with node 22

Thank you for publishing this package, it looks like exactly what I need to test that tooling updates don't break my packages. Today I tried running it on one of my project and found that diff2html could not cope.
Here is the relevant output:
❯ npx pkdiff ./rhds-tokens-2.0.1.tgz @rhds/tokens@2.0.0
Need to install the following packages:
pkdiff@2.0.1
Ok to proceed? (y) y
