PIDLookup: fix incorrect PDG convention - electron should not be -11

[veprbl]

Second iteration on #1442. None of the hadrons should be affected by convention, but electron is one of exceptions.

This was discovered in benchmark https://github.com/eic/physics_benchmarks/blob/cd616f2a92e5d59f9e94c27d9ad0a1b8c18daeef/benchmarks/dis/analysis/truth_reconstruction.py#L56
