tailwindcss example crashes when upgrading to tailwind 3.x

Hello and thankyou for the example: https://github.com/meteor/examples/tree/main/tailwindcss

It works perfectly well, however when I run the instructions to repeat this, I get

```json
"tailwindcss": "^3.2.4"
```

Which throws the following error:
```
Errors prevented startup:

While minifying app stylesheet:
app/client/main.css: PostCSS received undefined instead of CSS string

Your application has errors. Waiting for file change.
```

However, if i use:

```json
"dependencies": {
"@babel/runtime": "^7.17.9",
"autoprefixer": "^10.4.13",
"jquery": "^3.6.0",
"meteor-node-stubs": "^1.2.1",
"postcss": "^8.4.18",
"postcss-load-config": "^3.0.1",
"tailwindcss": "^2.0.3"
},
```

Then everything is is ok.
Are you able to share what combination of packages and versions will work with tailwindcss 3.x?

Thanks

Start with the Tailwind CSS example linked in the issue and reproduce the failure using tailwindcss 3.2.4, checking app/client/main.css and the listed dependency versions. Compare the working Tailwind 2 setup with the 3.x setup; done means the example starts without the PostCSS undefined-CSS error.
