fix symlinks for ansible when non-default version is installed
The issue is that before stage, other binaries are links to ansible:
bin/ansible-vault -> bin/ansible
bin/ansible-playbook -> bin/ansible
During stage, these get renamed with a suffix, like 3.6, but the
target of the symlink doesn't change:
bin/ansible-vault-3.6 -> bin/ansible
bin/ansible-playbook-3.6 -> bin/ansible
This either creates broken links if the package for the default
Python version is not installed or it creates links to the
wrong binary if it is.
Thank you Andreas Sommer for the fix!
