[PATCH 2/3] docs: restore left padding in preformatted blocks

[Rito Rhymes <rito@ritovision.com>]

Restore a small amount of left padding to preformatted blocks.

This improves readability because the preformatted block and its
container use different background colors, and when the first
character sits too close to that contrasting edge it is harder to
read.

This only changes the rendered left padding around the block. It
does not change the code itself or what gets copied from it.
