### Features

#### Add `--meta=pdm` option for generating PEP621 + PDM metadata

The default metadata is still `--meta=poetry`, which generates a
`pyproject.toml` file with Poetry-specific metadata.
This change adds the `--meta=pdm` option which includes
[PDM](https://pdm-project.org/latest/)-specific metadata, but also
standard
[PEP621](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#writing-pyproject-toml)
metadata. This may be useful as a starting point for other dependency
managers & build tools (like Hatch).

#### Add original OpenAPI `data` attribute to `Response` object

PR #767

In custom templates, you can now access a `response.data` attribute that
contains the original OpenAPI definition of the
response (Response Object or Reference Object).

#### Include the `UP` rule for generated Ruff config

This enables [pyupgrade-like
improvements](https://docs.astral.sh/ruff/rules/#pyupgrade-up) which
should replace some
`.format()` calls with f-strings.

### Fixes

#### Fix Ruff formatting for `--meta=none`

PR #940 fixes issue #939. Thanks @satwell!

Due to the lack of `pyproject.toml`, Ruff was not getting configured
properly when `--meta=none`.
As a result, it didn't clean up common generation issues like duplicate
imports, which would then cause errors from
linters.

This is now fixed by changing the default `post_hook` to `ruff check .
--fix --extend-select=I` when `--meta=none`.
Using `generate --meta=none` should now be almost identical to the code
generated by `update`.
