Drupal 10 off-canvas styles are broken

Problem/Motivation

The off-canvas reset replacement added in #3375606: Drupal 10 compatibility, style_selector_library_info_alter() is too aggressive in that it removes the reset entirely and only provides a replacement when style_selector elements are rendered.

Steps to reproduce

View the off-canvas sidebar or settings tray when a style_selector element is not present. The styles are broken.

Proposed resolution

Implement hook_css_alter() to replace the core file path with the path to the style_selector file.
