Some application control key name strings are displayed without the "AC" prefix, unlike similar strings

The Bug:

Some application control key name strings are displayed without the "AC" prefix, unlike similar strings.

These strings are the key names shown in the key binds menu. In 26.3 Snapshot 9, the translation keys key.keyboard.new and key.keyboard.save, added in 26.3 Snapshot 7 as "New" and "Save", were renamed in deprecated.json to key.keyboard.ac.new ("AC New") and key.keyboard.ac.save ("AC Save"), but kept their old text. When the game loads the language, this older text replaces "AC New" and "AC Save", so these two keys are displayed as "New" and "Save". Other application control keys are displayed with the "AC" prefix, for example "AC Back" and "AC Open", therefore introducing an inconsistency. The "AC" names were added in MC-311010.

Affected String(s):

Before reading the table, please note the following:

• Characters colored in GREEN are correct.

• Characters colored in RED are incorrect.

Steps to Reproduce:

1. Display any of the affected strings as listed above by using the command provided below and replacing "XYZ" with the string's translation key.

   /tellraw @s {"translate":"XYZ"}

   In game, the first two strings use the keys key.keyboard.ac.new and key.keyboard.ac.save, so use these keys for them instead.

2. Observe if the said strings contain the "AC" prefix.

Observed Behavior:

The "AC" prefix is missing.

Expected Behavior:

The "AC" prefix would be present.
