[isinyaaa]

good idea!

[tarilabs]

I've evaluated the potential of using an ad-hoc session with fee9326
but I'm not very happy with this translating into its own GH runner.

[tarilabs]

So I'm binding this to the

matrix.session == 'tests' && matrix.python == '3.12'

To avoid defining a new session and GHA runner just for having an archive of the dist
