Fix sass_binary target build with "npm_sass_library" as external npm …

…sass dependency

As we upgraded to angular v14 now, and switched to use @use based angular material sass API, we changed the sass_binary dependency from the [_theming.scss](bazelbuild/rules_sass#98) stylesheet to @angular/material, so updating the dependency accordingly should fix the build error of "Cannot find stylesheet to import - @use '@angular/material' as mat".
