I think the root of the problem is that we are publishing to a branch
which makes sense if we write the HTML by hand.

However we are generating it from multiples sources. So this doesn't
work well with Git.

Why not use the upload assets method?:

I guess a github action can be triggered by multiple sources, including
other actions and the assets from one action should be available in the
next.

I'm more familiar with GitLab, but this is basic build pipeline stuff,
so GitHub should support it.
