Minecraft Cursor

Fabric changes:

• Fixed some mods resetting the cursor back to system cursor (e.g., owo-lib resetting the cursor when opening the creative inventory #26).
• Shortened warning when Early Loading Screen mod is installed.

Note: Sorry Neoforge & Forge users, I tried to bring at least some of these compat features over there, but seems like I cannot even transform non-Mojang libraries (with Mixins) like ImGui.

For context, ImGui is the usual suspect for why the cursor is not changing or is being reset, as it is ran unconditionally by a lot of mods that use it.
