chore(deps): bump @livepeer/design-system to 1.1.2

Restores the subdued Button styling (subdued `primary` / `neutral` /
color-loop variants, `transparentWhite` / `transparentBlack` variants,
base styles) that Explorer has been rendering from the v1.1.0 tarball
for ~3 years. v1.1.2 is byte-identical to v1.1.0 for the Button block,
so this bump requires zero call-site code changes.

Background: the published v1.1.0 tarball contained Button styling that
had never existed in any commit of livepeer/design-system — it was
built from an uncommitted working tree in 2023 and diverged silently
from git main, which used a saturated variant form. Explorer could
never upgrade (v1.1.1 shipped with an empty `dist/` folder and is
unusable), so the divergence was invisible until someone tried to
build Explorer against design-system `main`.

v1.1.2 (livepeer/design-system#158) codifies the tarball state as the
committed source of truth so the repository and the shipped artifact
finally agree. This PR brings Explorer along for the ride.
