[cssg-plugin-assets] pathToFileURL() issue on Windows

[yannikrauter]

When working with contentful-ssg on macOS or Linux, everything works as expected. However, I have come across an error while trying to get my project to run on Windows.

I'm using contentful-ssg to pull my entries from Contentful, as well as the cssg-plugin-assets to also pull any assets. I believe the error I'm receiving is caused by the assets plugin and might have something to do with not using "url.pathToFileURL()", as described here.

After applying npx cssg fetch -v, the output log of my terminal looks like this (only when using Windows):

Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'c:'

I have tried various node versions and fixes to circumvent the issue but unfortunately, to no avail.

Node version: v20.11.1

Hugo version: v0.122
