Bump cssnano from 9.4.0 to 9.6.0

[dependabot]

Bumps cssnano from 9.4.0 to 9.6.0.

Release notes

Sourced from cssnano's releases.

v9.6.0

What's Changed

New Features

• feat(postcss-merge-longhand): merge row-gap/column-gap, overscroll-behavior-x/-y, flex-direction/flex-wrap, column-rule-* and equal overflow-x/-y into their shorthands when every target supports them

Bug Fixes

• refactor: remove cssesc dependency

• fix: improve escape handling in selectors

• fix: update postcss-calc

• fix: accept the optional leading rounding strategy of round(), such as round(up, 1s, 1s), when postcss-ordered-values orders animations and transitions and when postcss-merge-longhand folds shorthands. The rounding strategy must be separated by a comma, so round(up 1px, 2px) is no longer treated as valid.

Looks like cssnano is up-to-date now, so this is no longer needed.
