This is no longer the repository for Embedded Dart Sass. The embedded
compiler has been merged into [the primary Dart Sass repository], and further
releases will be included [as part of Dart Sass itself]. The embedded compiler
can be accessed by running sass --embedded.

For temporary solution, please update the available version in the document to max
1.62.1
