Fixed reading Parquet file on Windows

[zaleslaw]

Updated file path handling to use toURI().toString

This commit replaces string concatenation for file paths with the more robust toURI().toString across various methods and tests. This improves consistency and ensures proper URI formatting.

Fixes #1378

The method toUri() is called on resourcePath but should be toUri() with capital 'U' to match the standard Kotlin Path extension. It should be toUri() not toUri() - please verify this is the correct method name for the Path type.

Runs correctly on both Linux and Windows

I didn't know that toUri method put the file prefix. Sounds good for me 👍
