Optionally allow for widescreen content

[dylanh724]

Context

In an ultrawide, I feel like I'm missing out on unused screen space, notable for tables and longer lines of code that can't be broken up (eg: long cli ciphers).

Forgive me if there's already a way to do this, but it'd be nice to have an option for the middle section to stretch out with the screen further.

Proposal

• When going wider than standard HD, allow for the middle column to stretch content further out - it's currently locked at calc(100% - var(--pst-sidebar-secondary)) and probably some other calcs from parents. If I just change that calc to, say, width: 100% just to experiment, nothing happens
