Use Ruff implementation of PyDocStyle and isort

[scott-huberty]

closes #58

• Removed pydocstyle from dependencies.
• Removed pydocstyle from pre-commit.yaml
• Removed tool.pydocstyle from pyproject.toml
• Added tool.ruff.pydocstyle to pyproject.toml
• added "D" to the tool.ruff.lint select option, per the ruff docs
• ported 'D100', 'D104', 'D107' from the tool.pydocstyle add_ignore option to tool.ruff.lint.per-file-ignores
• Unlike in tool.pydocstyle, The tool.ruff.lint.pydocstyle ignore-decorators option expects a list of str, not just a str
• added click.group to ignore-decorators so that ruff does not raise an error for the docstring in template.commands.main.run (alternatively we could just make that docstring numpydoc compliant)
• did NOT port the match and match_dir options from tool.pydocstyle to tool.ruff.lint.pydocstyle, because these parameters dont exist in tool.ruff.lint.pydocstyle, and I think these configurations should already be covered by the tool.ruff configurations
• Added pre-commit to the test optional-dependencies.

Thanks a lot @scott-huberty
I pushed a couple more commits before merging, mainly:

• ignore-decorators supports "specified fully-qualified decorators." -> you actually need to give the full import path, e.g. template.utils._docs.copy_doc for each decorator.
• I removed some file exclusion to let ruff run on everything.
• I removed isort, last time I checked, the differences with ruff implementation were too important, but this is not the case anymore! 😄
• I pinned ruff to the latest version, 0.6.0 and above, as the PT rule set as some differences compared to 0.5.x.
