Restore duckdb_gdal_json.patch format

[geoyee]

When building using CMake according to CI commands, the only difference is that I used VS's sln instead of Ninja (cmake -G "Visual Studio 16 2019" ...). I received the following error (#738):

I think there is an issue with the format of duckdb_gdal_json.patch. I created a clean file, and now I can generate and compile normally.

Thanks!
