The ESP tool is being executed directly in the esp32 runner, assuming the tool is executable by itself. However, it would fail under Windows as subprocess.check_call() cannot execute Python scripts directly. The fix is to execute the Python interpreter and passing the script path as a command line parameter. Fixes #19098 Signed-off-by: Daniel Leung <daniel.leung@intel.com>
