Fixed it so the CI build UI

The UI stopped getting build by the CI. Updated the
workflow files to build the UI and upload it as an
artifact that people can use.

* Improved version command to contain additional version
information about the binary.
* Imported the workflow to reduce amount of duplicated work
* include branch name as part of version information.
* moved redundant task to local actions to improve reuse of workflow code

fixes #855
