[MC-255151] net.minecraft.client.Camera#getMaxZoom(double) issue

I don't think that " + (double)f3" in the line marked with " // <-- What?" is intentional. This should be removed. Ingame this leads to slightly wrong camera distances in the 3rd person views (front and back), if the camera hits an obstacle.
