Regression with switch to filesystem function

[ofTheo]

So I think the error with the nightly build is tied to the switch from ofFile::copyTo to fs::copy_file.
ofFile::copyTo creates the folder structure if it doesn't exist.

See:
https://github.com/openframeworks/openFrameworks/blob/master/libs/openFrameworks/utils/ofFileUtils.cpp#L957-L959

But fs::copy_file doesn't

So when the projectGenerator tries to copy the template file sortingExample/.vscode/c_cpp_properties.json over into sortingExample/.vscode/ it errors as the folder doesn't exist.

Suggestion we switch fs::copy_file to an internal copyFile call which mimics the old behavior or we revert to the old ofFile::copyTo as I am guessing this might be affecting other files as well.

quick fix using the static ofFile::copyFromTo as we were only using it in two places.
