Fix nested directory on windows

[anshulrgoyal]

The action uses the backslash () instead of slash (/) for the key on windows causing incorrect upload on S3

Is this ever going to be merged? I am trying to use this but running into the slash issue. It looks like this has been open and ready to merge for a year.
