ci: Explicitly set version when exporting the Conan recipe (#6264)

By default the Conan recipe extracts the version from `BuildInfo.cpp`, but in some of the cases we want to upload a recipe with a suffix derived from the commit hash. This currently then results in the uploading to fail, since there is a version mismatch.

Here we explicitly set the version, and then simplify the steps in the upload workflow since we now need the recipe name (embedded within the conanfile.py but also needed when uploading), the recipe version, and the recipe ref (name/version).
