Adding new kernel fails with python <3.8

[ileasile]

Fails because the unsupported feature is used in install script:

Installing kernel to /Users/pavel.gorgulov/Library/Jupyter/kernels/kotlin_JDK_11_kernel

    shutil.copytree(src, dst, dirs_exist_ok=True)
TypeError: copytree() got an unexpected keyword argument 'dirs_exist_ok'

Either state in the documentation that only python >= 3.8 should be used, or rewrite it to support lower versions.
