Check if creating branches in docs archives works as expected

I was browsing the site and the dropdown in particular, and realized that 18.2 and 18.1 point to the docs site, whereas 18.0 in the archives site.

18.0 is in the archives site indeed, since the branch is created.

However, I'd expect the 18.1 branch to be there as well. For the 18.2 release, the make create-archive-branch command should create the 18.1 branch (it creates the branch for the previous stable release).

I'm wondering if there's an error that's easily missed in the logs 🤔

The only thing I can think of is that maybe the local files are outdated and the command picks an old versions.json which is used to determine what branch to use. This might be a timing issue after all, as it depends how early you start the process (running make update effectively).
