Description of libraries inside actions.yml is wrong

[motya770]

Should be [{"pypi": {"package": "tqdm"}}, {"pypi": {"package": "xgbse==0.2.3"}},

instead of [{"pypi": "tqdm"}, {"pypi": "xgbse==0.2.3"},

` libraries-json:
description: >
JSON string containing a list of libraries (e.g. [{"pypi": "sklearn"}, {"pypi": "mlflow"}]) to
be installed on the cluster that will execute the notebook as a job.

  See docs at
  https://docs.databricks.com/dev-tools/api/latest/libraries.html#library
  for details on how to specify this input.`
