The Bug:

The "item.minecraft.smithing_template.netherite_upgrade.base_slot_description" string is missing a serial comma.

For a bit of context, a serial comma is a comma used after the penultimate item in a list of three or more items, typically before the words "and" or "or". For example within the sentence, "We went to the store and bought wheat, carrots, potatoes, and beetroots.", the serial comma is the comma present right after the word "potatoes".

Minecraft's source language, (which is English, United States), commonly makes use of this comma, and since it's present within several other strings throughout the game, this introduces an inconsistency.

Affected String:

Before reading the table, please note the following:

• Words colored in GREEN are correct.
• Words colored in RED are incorrect.

Steps to Reproduce:

1. Display the affected string as listed above by using the command provided below.

   /tellraw @s {"translate":"item.minecraft.smithing_template.netherite_upgrade.base_slot_description"}

2. Observe if the string utilizes a serial comma.
3. Take note as to whether or not the "item.minecraft.smithing_template.netherite_upgrade.base_slot_description" string is missing a serial comma.

Observed Behavior:

A serial comma is missing.

Expected Behavior:

A serial comma would be present.
