Resolved an error that occurs when using with sass 1.60.x

[mkusaka]

First of all, thank you for creating this wonderful CLI. I use it all the time and it has been a great help.

Currently, when used with the latest version of sass, which is 1.63.3, an error occurs.

This is likely due to breaking changes introduced by sass.

In this PR, we will avoid this by using the default when importing, if it exists, and not using the default if it doesn't.

[mkusaka]

note: I implemented this pattern because I confirmed that simply removing .default would cause it to stop working with versions prior to 1.60.x.

@mkusaka This is shipped in 2.1.2. Please could you try it?

I've just updated to version 2.1.2 in my workspace and verified that everything is functioning as it should 🎉.

I appreciate your support. 🙏
