Add workflow for HGCal v4

[mark-grimes]

Added a workflow to runTheMatrix that is an exact copy of Extended2023Muon (122xx) except that the geometry has been changed to

Extended2023HGCalV4,Extended2023HGCalMuonReco

The new workflow number is 148xx. This is (hopefully) a temporary workflow and the number should not be relied on in future.

Ping @boudoul.
