When we update the a sai package downing from a remote server, we need to update the version file as well currently, but the reproducible build feature is not enabled in master, it can only be detected when merging the code into the release branches, such as 202106, 202012, etc.
The reproducible feature is to reduce the build failure, not need to break the build when the version not specified. If version not specified, the best choice is to accept the version from remote server.

Why I did it
Skip to use the web proxy when the packages have been in the proxy server.
For sai packages or the other packages, we will upload the the proxy server directly, the reproducible will skip to check the site, not necessary to change the version files.
* Fix py3 version changed even version control enabled issue
* Add some comments and simplify the script
* Add the comment to explain how to get the not hooked command
