Update for ViaVersion v5.0

This updates ViaChatFixer for ViaVersion 5.0

I have not checked if this works on Sponge given changes relative to Sponge in ViaVersion.

Hi, thanks for your pull request, I didn't think ViaChatFixer was still in use after all this time!

Looks good, just about the Sponge version, as ViaVersion v5 only supports SpongeAPI v8, which is Minecraft 1.15, unless I miss something (I'm definitely not a Sponge expert!), old Sponge servers can't use ViaVersion v5, so Sponge support could now be removed?

I know very little about Sponge either but this sounds correct. I've removed Sponge support in the most recent commit.

Only thing I'm not sure about is how best to determine that the appropriate version of ViaVersion is loaded. This obviously won't work with v4.x but it will definitely try to load with it.

Great thank you 🚀 I also removed the various modules that were no longer needed with the removal of Sponge and changed the output to Java 8 again (ViaVersion still offers a Java 8 build and no recent Java features were used)

Checking for the com.viaversion.viaversion.api.type.Types class, introduced with ViaVersion 5 seems to be a good solution 😃
