CI create release and upload files on tag (#439)

* CI create release and upload files on tag

On tag creation, this creates a new release and uploads the corresponding compiled launcher and debug files.

* Remove leftover `ls`

* Remove condition to not build RCs

Release candidates should also be built and uploaded. The condition for not building them was a leftover from copy-pasting code.

* Move condition to parent

* Make sure files are in root of zip

Previously they were in a subfolder inside the zip

* Remove leftover content from copy/paste
