DYN-5709: publish version fix

[dnenov]

Purpose

Following up on a https://jira.autodesk.com/browse/DYN-5709, this PR addresses a bigger concern. The Publish Version experience has been broken for a while now. After a lengthy research and trying several options, the proposed solution is very simple.

Context - the retain folder structure option was introduced as an alternative way to publish a package. It was modeled after the existing and only way, which lead Dynamo predefine a set of 4 folders (bin, doc, dyf, extra), and allocate packages accordingly. As one of the steps, this flow would check and delete pre-existing files in the above locations before copying the files to a finalize package structure. This made sense, as the files would come from a separate place to be copied in this new package folder structure.

In contrast, the retain folder structure takes files and folders exactly as they are, and copies them to the default package folder, so the final package is loaded in Dynamo and ready to use. However, in case there is a folder already installed locally, and the user needs to submit it for the first time online, or submit it as a new version, the source files will be the same as the target files. In this case, it makes no sense to try to override the file with the same file, so we simply skip it.
