Mod description with single apostrophe leads to "Illegal format found" error in log

[3TUSK]

Minecraft Version: 1.20.5 - 1.21.1. Tested using 1.21.1.

NeoForge Version: Tested using 21.1.61; should happen on any NeoForge with version in range [20.5.0, 21.1.61]

Logs: N/A, no crashes happen

Steps to Reproduce:

1. Create a low-code mod with only neoforge.mods.toml given below

modLoader="lowcodefml"
loaderVersion="[1,)"
license="CC0-1.0"

[[mods]] #mandatory
modId="test_description_with_single_quote"
version="1.0.0"
displayName="Test Description with Single Quote" 
description="It's regression time!"

2. Add it to your mods directory
3. Launch game
4. Open Mod List screen
5. Confirm that the low code mod is loaded by finding it on your left-hand side
6. Click the low code mod entry to open details
7. Find this line in your log, timestamp may vary:

[18:46:26] [Render thread/ERROR] [ne.ne.fm.i1.FMLTranslations/CORE]: Illegal format found `It's regression time!`

Description of issue:

Similar to #734, if mod description contains an apostrophe (U+0027 APOSTROPHE), ExtendedMessageFormat, which is used by FMLTranslations, will see it as unterminated quoted string and throw IllegalArgumentException.

It was fixed in #686 for 1.20.4, but the fix for 1.20.5 and onward - #851 - only covers mod name, not mod description.

This regression was attested in Argon4W/EveryXHotpot@bb5458c.

It's still a problem even in 1.21.3.

🚀 This issue has been resolved in NeoForge version 21.4.7-beta, as part of #1739.

The issue is still present in the 21.1.92 version of Neoforge. Will the fix be ported to 1.21.1?
Every time a mod with a long description is selected from the menu the log gets filled with its content.
