ElectronPhotonSelectorTools: Update dnn menu for run 2
Updating dnn menu ATLASG-2652 , needs to be merged today as it should go into new PHYS ATLASDPD-2084 (does not change size just updates the dnn sel variable)
Also adding dnn to testEGIdentificationPoints for easier local testing (not in CI but might consider adding it in another MR?)
