Remove github release script

- Looking at our releases, https://github.com/Human-Connection/Human-Connection/releases, the ones created from our build server, are not sufficient.

As part of the deploy process, I have been manually creating the Releases in Github, using our CHANGELOG.md.... I propose we remove this script from our build server, as it's now breaking our master build and it's not being used.
