Replace clone with download about pinefarm

PineAPPL and MadGraph. In particular, for PineAPPL we need to install the C API, and it's not a great idea to ship it as Python package (but maybe I'm just wrong...).

I guess also vrap @scarlehoff ?

and to be more precise: let's not use latest, but a fixed version! to be specific for PineAPPL this would be import pineappl; pineappl.__version__ as defined by pyproject

[felixhekhorn]

latest release definetely

about which repos are we talking about? because all python stuff (eko, yadism) should come without repo (but via PyPI). If we're not using releases (everywhere) we could likewise give up on poetry ;-)

It seems that to clone a repository from GitHub now you always need to set credentials, whatever URL you are using.

It should be possible to clone with no credentials. That said, agree with the following:

It should be possible to clone with no credentials.

I thought so as well (for public repositories of course), but I was not able to do it with pygit2 and GitHub...

Ok, let's go for latest then! (unless @cschwan is strongly against it...)

[alecandido]

Ok, that might be fine as well

P.S.: for the non-python dependencies instead, I will hard-code versions in the package
