build(Hi.Sample.Wpf): move the version line to 3.2 and retarget HiAPI references

VersionPrefix follows the workspace onto the 3.2 line and the floating HiAPI
package references move from 3.1.* to 3.2.*, which is what the libraries now
publish. The build counter keeps running -- only the packages on the Gitea feed
restart, the same split as the 1.4 -> 3.1 move.

The last 3.1 build of this repo is tagged and kept alive on support/3.1.
