Update layout fluid prop to set max-width

Setting page container fluid prop to 'xl' to allow fluid/100%
container width until reaching the xl breakpoint. After
reaching the xl breakpoint, a max-width is set to the
container.
This will make sure that the page content doesn't stretch
into an unreasonable layout on wide viewports.
