[bug]: npx shadcn init doesn't work when variables are in tailwind.config.js

[nicksmithr]

Describe the bug

When running npx shadcn@latest in a project which has variables within the tailwind.config.js theme.extend, it fails to run with:

Error replacing tree: The children of the old and new trees were expected to have the same count (8:21).

There's an issue with ts-morph.

E.g. with:

const defaultTheme = require('tailwindcss/defaultTheme');

export default {
    content: ['./src/**/*.{astro,html,js,jsx,md,mdx,svelte,ts,tsx,vue}'],
    theme: {
        extend: {
            fontFamily: {
                sans: ['Plus Jakarta Sans Variable', ...defaultTheme.fontFamily.sans],
                mono: ['Silkscreen', ...defaultTheme.fontFamily.sans]
            },
    plugins: [require('tailwindcss-motion')]
};

The ...defaultTheme is causing it to fail. I imagine the parser isn't accounting for variables inside the config, but I think it's quite a common setup
