ERRORS: Having trouble rendering/compiling css template + Browser queries must be an array or string. Got object.

Enabling the plugin via `eleventyConfig.addPlugin(lightningCSS);` in `.eleventy.js` produces the following error:

````

[11ty] 2. Having trouble compiling template ./src/Box.css (via TemplateContentCompileError)
[11ty] 3. Browser queries must be an array or string. Got object. (via BrowserslistError)

If I rename or delete `Box.css` I get the same error, but for the next CSS file in my project (`/src/Center.css`).

I'm configuring `browserslist` in my `package.json`, but I've also tried the default method and produced the same error.

[Contents of `.eleventy.js`](https://github.com/5t3ph/eleventy-plugin-lightningcss/files/13572887/eleventy.txt)

The error originates in the plugin's compile function at .eleventy.js line 100, where browserslist receives an object instead of an array/string. Start by examining the plugin's source to see how the browserslist query is constructed. Check the project's package.json for browserslist configuration and ensure it's valid. Run the plugin in a minimal Eleventy project to reproduce the issue and trace the data flow.
