Addon Help

I need addon help. Can someone edit the following addon to make it work?: https://drive.google.com/file/d/1QO9JkXWSJxYf7J--eZ-P24YHKENntvgI/view

Its supposed to:
-Add the tag of "Infected" to all zombie type mobs(including players with "Infected" tag)
-Add the tag to players who are 1 block away
-Make "Infected" players burn in daylight
-not allow zombies to have human food
-Villagers run from players with "Infected" tag
-Iron golems attack players with "Infected" tag
-Baked potatoes change to "Baked brain"
-You can remove the "Infected" tag by curing a player like a normal zombie
-Infected players make zombie groans
