Fix named attributes in legacy failing when reading back data from Module Metadata

[shartte]

We current have a bug where depending on a Mod that was published by MDG Legacy fails, due to that Mod containing our mappings attribute with the value "srg".

Gradle seems to be unable to map that back for some reason.

* What went wrong:
Execution failed for task ':compileKotlin'.
> Could not resolve all files for configuration ':compileClasspath'.
   > Could not resolve dev.icosider:dripper-forge:1.20.1-1.0.0.
     Required by:
         root project :
      > No enum constant net.neoforged.moddevgradle.legacyforge.internal.MinecraftMappings.srg
