[BUG] Cannot transpile CSS files when upgrading to Hugo v0.123.x

Describe the bug

When upgrading to Hugo v0.123.x, certain Hinode modules fail to transform their SCSS input files. These errors cascade to downstream modules too.

To reproduce

Upgrade the Hugo binary to the latest version (currently v0.123.6) and build the site. Visit gethinode/mod-bootstrap#52 for an example.

Log file

As an example, the mod-bootstrap module fails with the following error:

Error: error building site: TOCSS-DART: failed to transform "style.app.scss" (text/x-scss): "/home/runner/work/mod-bootstrap/mod-bootstrap/assets/scss/modules/bootstrap/_mixins-dart.scss:9:8": Can't find stylesheet to import.
