Fix AUTO_DEVOPS_CHART file download
After unpacking the custom chart file - helm 3 keeps the full file name (with the file extension) as the folder name.
Original error from auto devops:
$ auto-deploy download_chart
"stable" has been added to your repositories
"bitnami" has been added to your repositories
Downloading remote chart 'https://gitlab.com/alekseyp/auto-deploy-app/-/archive/master/auto-deploy-app-master.tar.gz'...
mv: can't rename 'auto-deploy-app-master': No such file or directory
Local test results:
$ helm pull "https://gitlab.com/alekseyp/auto-deploy-app/-/archive/master/auto-deploy-app-master.tar.gz" --untar
$ ls -lart | grep auto-deploy
