refactor(docs-infra): simplify the CSS rules for styling the "collapsed/expanded" sidenav icons (#40427) 

This commit simplifies the styling of the "collapsed/expanded" icons in
sidenav nav-items with children by consolidating the CSS rules in one
block (instead of having duplicate blocks for different levels).
