Set API Doc Version in generate release zip script (#3268)

* Port the change from release/3.2 branch (9b6e07d)

* Without explicitly set the version, the tool intelligently picks the version number from the podspec file. This may be OK unless we forgot to update the version in the podspec or we cannot update the version until the release time.

* Explicitly set the version number when generating the doc. If the version is not specified, there will be no version shown in the doc.
