Trigger workflow in argus-docker on release

[johannaengland]

Will trigger the workflow added in Uninett/argus-docker#6.

Another part to close Uninett/argus-docker#4.

To get this to work we need to install a GitHub App that has the permissions to trigger workflows in Argus. This app will be used by the used GitHub action create-github-app-token to create a token with the necessary permissions.

Looks good to me but I think @lunkwill42 should also have a look.

I've had a look, and it seems like the expected approach to me. Haven't built this type of solution with GitHub before, so can't say for sure if it will work before we try it the first time.
