Force use of Jira Software V8.x

[tyndyll]

Fixes: #61

Updated prepare script to explicitly pull the V8.x version of the Atlassian Software tarball. Removed unused script parameter and forced the Dockerfile to use the environmental variable to pull the code rather than having to update it in place

NOTE: This resolves the 8.x version problem, as the JSON file being pulled currently has the most recent version of 7.x and 8.x available. It would be possible to set up additional dockerfile for both versions (e,g. either 2 separate Dockerfiles or using ARG parameters), but this would require some additional setup either in the DockerHub build to tag the versions appropriately, or to push from CircleCI to DockerHub.

Happy to help, but outside the scope of this PR :)

WRT merge conflict - this can be merged using my solution. The current master is the hard coded version from CI
