dataPaths.json broken, fix it

I see... Weird, I used incrementVersion.js so I've no idea why those mistakes are there

[CreeperG16]

It seems CI is failing because BDS isn't starting up in time? Not entirely sure what's up with that

Edit: It can't seem to find the BDS download link

I'm looking for it now but something will probably need to be changed in minecraft-bedrock-server or whatever code downloads BDS

[extremeheat]

Please don't rename packets unless it's a different packet (same for fields holding same data), this unnecessarily breaks code compatibility

[extremeheat]

But if there does need to be a rename for something, it should be backported to the old versions. I've fixed this one.

[extremeheat]

Thanks for working on this!
