Fractal-server

* SSH SLURM executor:
* Handle early shutdown in SSH executor (\1696).
* Task collection:
* Introduce a new configuration variable `FRACTAL_MAX_PIP_VERSION` to pin task-collection pip (\1675).

* API:
* When creating a WorkflowTask, do not pre-populate its top-level arguments based on JSON Schema default values (\1688).
* Dependencies:
* Update `sqlmodel` to `^0.0.21` (\1674).
* Add `uvicorn-worker` (\1690).

> WARNING: The `pre_submission_commands` SLURM configuration is included as an
> experimental feature, since it is still not useful for its main intended
> goal (calling `module load` before running `sbatch`).

* SLURM runners:
* Expose `gpus` SLURM parameter (\1678).
* For SSH executor, add `pre_submission_commands` (\1678).
* Removed obsolete arguments from `get_slurm_config` function (\1678).
* SSH features:
* Add `FractalSSH.write_remote_file` method (\1678).

* SSH SLURM runner:
* Refactor `compress_folder` and `extract_archive` modules, and stop using `tarfile` library (\1641).
* API:
* Introduce `FRACTAL_API_V1_MODE=include_without_submission` to include V1 API but forbid job submission (\1664).
* Testing:
* Do not test V1 API with `DB_ENGINE="postgres-psycopg"` (\1667).
* Use new Fractal SLURM containers in CI (\1663).
* Adapt tests so that they always refer to the current Python version (the one running `pytest`), when needed; this means that we don't require the presence of any additional Python version in the development environment, apart from the current one (\1633).
* Include Python3.11 in some tests (\1669).
* Simplify CI SLURM Dockerfile after base-image updates (\1670).
* Cache `ubuntu22-slurm-multipy` Docker image in CI (\1671).
* Add `oauth.yaml` GitHub action to test OIDC authentication (\1665).

This release fixes a SSH-task-collection bug introduced in version 2.3.1.

* API:
* Expose new superuser-restricted endpoint `GET /api/settings/` (\1662).
* SLURM runner:
* Make `FRACTAL_SLURM_SBATCH_SLEEP` configuration variable `float` (\1658).
* SSH features:
* Fix wrong removal of task-package folder upon task-collection failure (\1649).
* Remove `FractalSSH.rename_folder` method (\1654).
* Testing:
* Refactor task-collection fixtures (\1637).

> **WARNING**: The remove-remote-venv-folder in the SSH task collection is broken (see issue 1633). Do not deploy this version in an SSH-based `fractal-server` instance.

* API:
* Fix incorrect zipping of structured job-log folders (\1648).
