Use new minio.MinioAdmin client in test suite and update minio server version

[sjperkins]

The latest minio python client changed MinioAdmin to directly communicate with minio servers, instead of via the mc client binary. This PR updates the testing framework to use the new interface and no longer installs mc when testing. The minio server version has been updated to 11 November 2023.

Weekly cron job failed on newer python client here: https://github.com/ratt-ru/dask-ms/actions/runs/6844991970

• Tests added / passed

  $ py.test -v -s daskms/tests

  If the pep8 tests fail, the quickest way to correct
  this is to run autopep8 and then flake8 and
  pycodestyle to fix the remaining issues.

  $ pip install -U autopep8 flake8 pycodestyle
  $ autopep8 -r -i daskms
  $ flake8 daskms
  $ pycodestyle daskms
  

• Fully documented, including HISTORY.rst for all changes
  and one of the docs/*-api.rst files for new API
