Latex displays will be aligned left in Jupyterlab

[Kwankyu Lee]

By the positive-reviewed ticket #32942,

    https://trac.sagemath.org/ticket/32942

latex displays will be aligned left in Jupyterlab, by default. 

We made this change to align with the behaviors of latex displays elsewhere, in particular, in classic Jupyter notebooks.

But if you prefer the old behavior, you can of course set your personal preference as described in the ticket.

Thank you.
