How do I change this Summon command to work with 1.20.5?

Question

I need help with changing a summon command to work in 1.20.5. The command appears to be correct, however, when I summon the mob it has armor/weapons but the enchantments don't work.

The command is:

/summon zombified_piglin ~1 ~ ~-2 {CustomName:"\"Bank Guard \"",Team:Blue, Tags:[BAUnit1_B],PersistenceRequired:1,HandItems:[{Count:1,id:golden_sword,tag:{Enchantments:[{id:sweeping_edge,lvl:4},{id:unbreaking,lvl:3}]}},{}],ArmorItems:[{Count:1,id:golden_boots,tag:{Enchantments:[{id:protection,lvl:1}]}},{Count:1,id:golden_leggings,tag:{Enchantments:[{id:protection,lvl:1}]}},{Count:1,id:golden_chestplate,tag:{Enchantments:[{id:protection,lvl:1}]}},{Count:1,id:golden_helmet,tag:{Enchantments:[{id:protection,lvl:1}]}}],IsImmuneToZombification:1b}

Also can you please explain how it works so that I can apply to all my other summon commands I use in my map I am creating? I don't need an example of necessarily every attribute in this command just anything that may differ in how it is typed.

In 1.20.5, NBT tags (the tag element) in items have been replaced with components. You will need to convert your command.
For example, the sword your entity carries:

{Count:1,id:golden_sword,tag:{Enchantments:[{id:sweeping_edge,lvl:4},{id:unbreaking,lvl:3}]}}

Would become:

{Count:1,id:golden_sword,components:{"minecraft:enchantments":["minecraft:sweeping_edge":4,"minecraft:unbreaking":3]}}

or

{Count:1,id:golden_sword,components:{"minecraft:enchantments":{"levels":["minecraft:sweeping_edge":4,"minecraft:unbreaking":3],"show_in_tooltip":true}}}
