Add more info to Fabric's geyser dumps (#4175)

* Added onlineMode, platformName, and Minecraft version to dump - renames platformVersion to loaderVersion since that is more fitting to modded structure

* rename loaderVersion back to platformVersion

* address review by @Konicai

* Fix geyser dump creation (regression from the syntax/annotation PR)
