Describe the bug
Due to the \n at the start of the contributors section in the fabric.mod.json the file produced has a new line in the middle of a string therefor is out of JSON specification and wont parse on many JSON parsers/validators

To Reproduce
Paste the `` from the compiled jar into a JSON validator (EG: https://jsonlint.com/)

Expected behavior
The file follows specification and validates

Environment

• OS: N/A
• Java Version: N/A
• Minecraft Version: 1.20.1
• Fabric/Quilt Version: N/A
• Fabric API/QFAPI+QSL Version: N/A
• Mod Version: 0.7.3

This is intended as the mod "Mod Menu" parses the newline character and creates a new line. I did this since it looks better ingame. \n is a valid character in JSON specification as it is essential for formatting text within a string. The JSON validators which are erroring are poorly made and parsing it as an actual new line instead of part of the string that it is contained in.
