README - fix charge in GenParticle example

[eduardo-rodrigues]

There was a trivial typo and the README example violated charge conservation ;-). While at it I updated a couple of masses to the PDG 2021 values.

There may be other places where the K*0 -> K+ pi- example is used ... to be checked.

@jonas-eschle, can this trivial fix get merged? Advance thanks.

Sure! I actually wanted to directly replace it with particle, that make more sense, I guess you agree?
But let's merge it and we can make a new PR for that anyways

Thanks a lot for the PR!

A looong time ago we talked about that and you said that a simple example was a good thing, not to "convolve" with functionality of a different package. I think you had a point - the basic example should be a "bare example". This being said, another example together with the ecosystem is worth having as part of a little notebook or the Scikit-HEP tutorials, and we can work on that aside this MR here. Thanks for the swift reminder :-).
