fix: wrap binary path resolution with fileURLToPath

[jderochervlk]

The extension was failing to correctly resolve the path on Windows.

node:internal/modules/esm/load:188
    throw new ERR_UNSUPPORTED_ESM_URL_SCHEME(parsed, schemes);
          ^

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

Adding fileURLToPath uses node's built in way to normalize the file URL so it works across platforms.

...as well as ensuring a cross-platform valid absolute path string

I tested this out on Windows and the extension now works.
