Add workflows to reconstruct HGCal using PandoraPFA

[mark-grimes]

Creates two new workflows to use HGCal v5 but using PandoraPFA in the reconstruction. Workflows are exactly the same as the normal Extended2023HGCalMuon except that this customisation function is used:

RecoParticleFlow/PandoraTranslator/customizeHGCalPandora_cff.cust_2023HGCalPandoraMuon

Numbers are 156xx for 0 pileup; and 158xx for 140 pileup.
Also fixed some whitespace.

@boudoul, I'd be interested if you have a better way of implementing this. I just replicated the Extended2023HGCalMuon workflows and changed the customisation function. There is obviously a lot of duplication so perhaps you have a better solution?
Also, I wasn't sure if some of the older workflows could be replaced, so played it safe and added new ones.

please test

(new workflows aren't in the test but I might as well check I haven't messed up the others)

The tests are being triggered in jenkins.

For the record, workflows 15600 and 15800 run all 3 steps fine. I'll wait until after #8008 is merged though because there could be a conflict (easier for me to change this PR than fix conflicts in #8008).
