ImmersiveMC isn't just about minimizing GUI usage, but about making Minecraft as a whole more immersive, mainly through the use of removing GUIs. The README should be adjusted to account for this.

We can softly depend on #23 here, as it would be a great GIF to add to the README to demonstrate this

Also want to change the GIFs in the README to the following (in-order):

• Immersive crafting table usage outside of VR
• Ranged pickup from in VR
• Immersive chest usage in VR

It shows off more parts of the mod, and highlights more of the mod's stronger-suits.
