ansible/changelogs/fragments/copy_keep_suffix_temp.yml

bugfixes:
  - copy action now ensures that tempfiles use the same suffix as destination, to allow for ``validate`` to work with utilities that check extensions.
  - copy action now also generates temprary files as hidden ('.' prefixed) to avoid accidental pickup by running services that glob by extension.
  - template action will also inherit the behavior from copy (as it uses it internally).
