"no such file or directory" - when appDir is a subdirectory

[ionous]

when appDir points to a subdirectory:

const appDir = path.resolve(__dirname, 'site');
const hugoOutDir = path.resolve(__dirname, 'public');
const hugoConfigFileName = 'config.toml';
export default defineConfig({
  plugins: [
    hugoPlugin({ appDir, hugoOutDir, hugoConfigFileName })
  ]
});

hugoPlugin will fail to load the config ( resulting in the stack below ) because the request to read the config doesn't include the path to the app dir.

modifying the line as follows, seems to fix the issue.

// import path from 'path'; 
const configString = readFileSync(path.join(appDir, configFile), "utf-8");

an alternative fix might be to remove the configFile filtering at the top of getHugoConfig(), and then the configFile could be an absolute path. ( readFileSync will fail if the file doesnt exist anyway )

I have a similar problem when config is in a subdirectory.

e.g.

my-project/
└── config/
    ├── _default/
        └── config.toml
    └── production/
        └── config.toml

This is the recommended approach to split config by environment as per Hugo docs.
