bugfixes:
  - terraform - fix ``current`` workspace never getting appended to the ``all`` key in the ``workspace_ctf`` object (https://github.com/ansible-collections/community.general/pull/5735).
  - terraform - fix ``terraform init`` failure when there are multiple workspaces on the remote backend and when ``default`` workspace is missing by setting ``TF_WORKSPACE`` environmental variable to the value of ``workspace`` when used (https://github.com/ansible-collections/community.general/pull/5735).
