fix failing download tasks.txt for gtimelog

* The download task failed, as the config directory was not created before, so a check for the directory was added to the playbook. If the check fails, the directory will be created for the user.
* The `ansible_env.USER` variable was used, as `ansible_user` was not available on the Debian 11 testing system.
* The initial `become: true` has been removed, as this was chaning the `USER` environment to `root` so that the user could not use the downloaded file

checked that this is running fine on a fresh install of Debian 11 in a VM.
