text: Title: [DOC-FIX] Document supported formats for `artifact_uri` in `mlflow.artifacts.download_artifacts`
  Body: ### Willingness to contribute
  
  No. I cannot contribute a documentation fix at this time.
  
  ### URL(s) with the issue
  
  https://www.mlflow.org/docs/latest/python_api/mlflow.artifacts.html#mlflow.artifacts.download_artifacts
  
  ### Description of proposal (what needs changing)
  
  The documentation for <code>mlflow.artifacts.download_artifacts</code> mentions that the <code>artifact_uri</code> parameter can take on various forms, such as <code>runs:/500cf58bee2b40a4a82861cc31a617b1/my_model.pkl</code>, <code>models:/my_model/Production</code>, or <code>s3://my_bucket/my/file.txt</code>. However, it would be helpful to provide a more explicit documentation of the supported formats for <code>artifact_uri</code> using regex expressions.
  
  Additionally, if the following forms are also valid for artifact_uri, they should be explicitly mentioned in the documentation:
  
  ```
  https://<host>:<port>/mlartifacts
  http://<host>/mlartifacts
  mlflow-artifacts://<host>/mlartifacts
  mlflow-artifacts://<host>:<port>/mlartifacts
  mlflow-artifacts:/mlartifacts
  
  models:/<name>/<version>/path/to/model
  models:/<name>@alias/path/to/model
  ```
  
  ### Benefits
  Providing a clear and explicit documentation of the supported formats for artifact_uri would help users understand what types of URIs are accepted by the function, reducing errors and improving overall usability.
