Cosmetics: Please capitalise Python in the commit log headline. Also, this change does not really concern only CI, but the client package functionality too, especially when you think of reana-commons and reana-client. Hence the scope would be better build(python) .

For example, see a past commit here:

build(python): drop support for Python 3.6 and 3.7 

This would call for using:

build(python): add support for Python 3.13
