ChatScreenMixin: switch to KeyEvent param (MC 1.21.9+ input refactor)

CI on 3b5e555 revealed:
- net.minecraft.client.renderer.RenderType moved to
  net.minecraft.client.renderer.rendertype; use RenderTypes.lines() factory.
- Camera.position() returns Vec3, not Vector3fc as I guessed.

OrderedSubmitNodeCollector, submitShapeOutline, Shapes.block/box,
LevelRenderEvents.AFTER_TRANSLUCENT_FEATURES — all compiled cleanly.
