Output file configuration option

[kieran-ryan]

Provide a --output-file configuration option - matching ruff - to specify file to output the linter output rather than the user handling through other means. Standardises configuration across Astral toolchains.

For context. The --output-file was added in https://github.com/astral-sh/ruff/issues/2388, but it's not sufficient for the use case of most users who want multiple outputs in CI.
