Fix the nightly image.

[mauritsvanrees]

I have daily been getting an error about the nightly image job failing.

It fails with: ModuleNotFoundError: No module named 'pkg_resources' This is because we have a too new setuptools version, which fails with any version of zc.buildout. And we need zc.buildout in our pip-from-buildout-coredev.py helper script.

Actually we could probably rewrite this to use code from plone.releaser. Or really nothing like that should be needed, because the coredev buildout already keeps the pip files up to date.

So this part could need a bit of rethinking. Also see if we want to maintain a nightly image at all. The workflow runs go back to June last year, and I don't see a single one that passes. They all seem to have the same error.

Anyway, let's fix the immediate error by explicitly using setuptools 81.

Also upgrade other versions:

• Python 3.13 to 3.14
• Plone coredev branch 6.1 to 6.2
• Latest from requirements.txt
• Update other packages, like pip and Relstorage

FWIW, locally the nightly image now works fine. make image-nightly and then docker run -p 8080:8080 plone/plone-backend:nightly gives me a backend where I can create both Classic UI and Volto sites, and they seem to have the expected versions:

fwiw, I thought we already decided to stop releasing the nightly image. As far as I know no one is using it.

Mostly I wanted to get rid of the daily mail that I got for a failing job that was easy enough to fix.

At least there is a nightly tag now that is up to date:

Let me open an issue for discussing (or confirming) if we want to remove the nightly job.
