Openml

This is a minor release to support several hotfixes and technical debt.

* MAINT 1280: Use the server-provided ``parquet_url`` instead of ``minio_url`` to determine the location of the parquet file.
* ADD 716: add documentation for remaining attributes of classes and functions.
* ADD 1261: more annotations for type hints.
* MAINT 1294: update tests to new tag specification.
* FIX 1314: Update fetching a bucket from MinIO.
* FIX 1315: Make class label retrieval more lenient.
* ADD 1316: add feature descriptions ontologies support.
* MAINT 1310/1307: switch to ruff and resolve all mypy errors.

**IMPORTANT:** This release paves the way towards a breaking update of OpenML-Python. From version 0.15, functions that had the option to return a pandas DataFrame will return a pandas DataFrame by default. This version (0.14) emits a warning if you still use the old access functionality.

More concretely:

* In 0.15 we will drop the ability to return dictionaries in listing calls and only provide pandas DataFrames. To disable warnings in 0.14 you have to request a pandas DataFrame (using `output_format="dataframe"`).
* In 0.15 we will drop the ability to return datasets as numpy arrays and only provide pandas DataFrames. To disable warnings in 0.14 you have to request a pandas DataFrame (using `dataset_format="dataframe"`).

Furthermore, from version 0.15, OpenML-Python will no longer download datasets and dataset metadata by default. This version (0.14) emits a warning if you don't explicitly specify the desired behavior.

Please see the pull requests 1258 and 1260 for further information.

* MAINT 1246: Add a warning that warns the user that checking for duplicate runs on the server cannot be done without an API key.

* ADD 1028: Add functions to delete runs, flows, datasets, and tasks (e.g., openml.datasets.delete_dataset).
* ADD 1144: Add locally computed results to the OpenMLRun object’s representation if the run was created locally and not downloaded from the server.

* FIX 1198: Support numpy 1.24 and higher.
* FIX 1216: Allow unknown task types on the server. This is only relevant when new task types are added to the test server.
* MAINT 1155: Add dependabot github action to automatically update other github actions.
* MAINT 1199: Obtain pre-commit’s flake8 from github.com instead of gitlab.com.

* MAIN 1088: Do CI for Windows on Github Actions instead of Appveyor.
* MAINT 1104: Fix outdated docstring for ``list_task``.
* MAIN 1146: Update the pre-commit dependencies.
* ADD 1103: Add a ``predictions`` property to OpenMLRun for easy accessibility of prediction data.
* ADD 1188: EXPERIMENTAL. Allow downloading all files from a minio bucket with ``download_all_files=True`` for ``get_dataset``.

* ADD 895/1038: Measure runtimes of scikit-learn runs also for models which are parallelized via the joblib.
