Add an Argilla annotation stack component

[strickvl]

Use the huggingface spaces module on the Terraform registry to add the option to deploy an Argilla annotation stack component as part of your mlstack.

The feature / PR would include:

• full support for the component
• updates to documentation where needed (possibly needs a separate section in the docs for these non-core cloud components)
• possible inclusion in the test suite if possible without too much overhead
