Description

Sass interpolations (https://sass-lang.com/documentation/interpolation) are parsed correctly, but stringify() removes them, resulting in incorrect code.

Steps to reproduce:

const tree = sast.parse('width: calc(100% - #{2 * $spacer})', { syntax: 'sass' });
console.log(sast.stringify(tree));

// should output: width: calc(100% - #{2 * $spacer})
// current output: width: calc(100% - 2 * $spacer)

This happens for both sass and scss.

Research direction
Examine the stringify function in the source code to see how interpolation nodes are handled. Identify the missing serialization logic and add it.
