chore: recomposition demo, updates Camera

[CaolanCode]

Hello,

In the recomposition demonstration the camera position is not updated with the marker position.
I have updated the camera position when the marker position is changed.
I've also used the location "signapore4" as it wasn't used.

Thank you for opening a Pull Request!
