[1.20.1] setTag, hasTatg and related methods missing in ItemStack

[Zkera]

Hello, I'm trying to make my first mod. Now I'm trying to make an item that would save the type of animal that I right-clicked on with the item and display it in the lore of the item. I thought that this should be implemented through NBT tags and started looking at methods.
In all the guides that I looked at and in the mods from GitHub, the setTag method was used to install new tags, but my IDE highlights this method in red, and when assembling, it gives an error. Same with hasTag and getOrCreateTag().

I use VS Code, 47.3.1 forge version, tried to update to 47.3.5.
Sorry for bad English, I use Google translator.
