Allow Positivity to have multiple Q2

[Radonirinaunimi]

This extends the POS generation to allow for multiple Q2. For this, the pinecards need to be changed as:

hadron_pid: 2212
lepton_pid: 11
pid: 21
kinematics:
  - x: 4.9999999999999998e-07
    q2: 5.0
  - x: 1.9407667236782136e-06
    q2: 15.0
...

The legacy pinecards are always supported for backward compatibility.

pinefarm change seems ok - but what is that py3.9 error? any idea @Radonirinaunimi ? poetry itself seems to be installed fine (at least it claims so) - or actually maybe not: comparing to the py3.10 output I can still see some lines being written ... weird

I don't really have an idea. I am thinking that this might be similar to python-poetry/poetry#1081 or python-poetry/poetry#8226. But I think this is a poetry problem as I don't know what in the changes could have triggered that.

so the poetry problem dissolved back to nothing where it came from 🙈

@kamillaurent please review this so we can merge
