Bug Title:
Invalid Escape Sequence \n in tellraw Command

Description:
In the Minecraft Snapshot version 25w02a, using the escape sequence \n in the tellraw command results in an error. Instead of interpreting the sequence correctly, the game throws a syntax error:

Error Message:

Invalid escape sequence '\n' in string at position 33

Example:

/tellraw @p ["Line 1",\{"text":"\n"},"Line 2"]

Expected Behavior:
The text should be correctly interpreted and displayed across two lines, like this:

Line 1

Line 2

Actual Behavior:
The command results in an error, and the escape sequence \n is not accepted. Instead, the error points to an invalid escape sequence in the JSON string.

Additional Information:

• Version: Minecraft Snapshot 25w02a
• Mode: Tested in singleplayer.
• Other Escape Sequences: It is unclear whether other escape sequences are also affected.

Steps to Reproduce:

1. Open a world in Minecraft Snapshot version 25w02a.
2. Execute the following command:
   /tellraw @p ["Line 1",\{"text":"\n"},"Line 2"]
3. Observe that the error message appears and the command fails to execute.

Expected Result:
The game should process the escape sequence \n and display the text on two separate lines.

Actual Result:
The error message indicates an invalid escape sequence, and the command does not execute.

Note:
This may indicate that the tellraw JSON implementation does not support or correctly process escape sequences like \n.
