Added

• Added support for translation memories in text translation via
  translation_memory and translation_memory_threshold parameters in
  translate_text().
• Added list_translation_memories() method to the DeepLClient class for
  listing available translation memories.
• Added --translation-memory-id and --translation-memory-threshold CLI
  arguments.

Fixed

• Fixed "gitlab release" CI job to explicitly set the release-cli image, avoiding issues with missing $HOME from the global image.
