Request: add REMARK with AlphaFold version and model used in every output PDB file

[lucajovine]

I guess the subject says it all! But really, I think this would be a simple but useful tweak to have, which would make things much easier when one is trying to reconstruct things a posteriori and possibly try to reproduce them. Something like:

REMARK ALPHAFOLD 2.3.2 (PARAMS_MODEL_1_MULTIMER_V3)

would remove all possible uncertainties.
