Typos in the Brusselator PDE tutorial

[dockerytong]

Missing comma and wrong parameter name while in discretization:

"discretization = MOLFiniteDifference([x=>dx, y=>dy], t, approx_order=order grid_type=center_align)"

Which should be :

"discretization = MOLFiniteDifference([x=>dx, y=>dy], t, approx_order=order, grid_align=center_align)"

Thank you! While you're here would you like any help solving a system?
