I’m upgrading Bud from v5 to v6. Everything is going fine expect a plugin is shown an error on the `bud.config.mjs`. The plugin is `svg-spritemap-webpack-plugin`.

I try to use it like this on the config:

```
export default async (app) => {
  / **other configurations here** /

  await app.use(new SVGSpritemapPlugin())
  
  / **other configurations here** /
```

The error shown in the editor is:

```
Argument of type 'SVGSpritemapPlugin' is not assignable to parameter of type 'Extension<any, any> | Constructor | ExtensionLiteral | (Extension<any, any> | Constructor | ExtensionLiteral)[]'.
  Type 'SVGSpritemapPlugin' is not assignable to type 'ExtensionLiteral'.
    Types of property 'apply' are incompatible.
      Type '(compiler: Compiler) => void' is not assignable to type '(compiler?: Compiler) => unknown'.

```

I don’t know if this error has to do with the Bud library or the `svg-spritemap-webpack-plugin`.

Why are you running your bud config through TypeScript? Do you have `node` aliased to `ts-node` globally or something?
