I'm not familiar with the infrastructure that will host the release or how that works but the changes in this PR seen fairly minimal and self-evident.

The only concern I can think of is that it seems that the same credentials are used for publishing both master nightly and tagged release artefacts and if there is somewhere in the nightly setup a weakness through which the credentials could be obtained then the damage would not be limited to nightly builds but could also be used to compromise actual releases.

@ximon18 Thanks for the review. Yeah thats a fair point, however, I will keep the setup as is for now as it was like this before as well. I think this can still be improved later on.
