Support configuration in [tool.biome] section of pyproject.toml

[kdeldycke]

Biome is a fantastic tool and with #8818 on the horizon, it starts to play nice with the Python ecosystem.

To integrate even more with Python projects, it would be cool to have biome source its configuration from a [tool.biome] section in pyproject.toml.

Other non-Python tools are supporting this, probably to increase adoption of their own tools in the Python world. See:

• [tool.ruff]: https://docs.astral.sh/ruff/configuration/#configuring-ruff (Rust)
• [tool.typos]: https://github.com/crate-ci/typos/blob/master/docs/reference.md (Rust)
• [tool.uv]: https://docs.astral.sh/uv/concepts/configuration-files/ (Rust)
• [tool.ty]: https://docs.astral.sh/ty/ (Rust)
• [tool.maturin]: https://www.maturin.rs/config (Rust)
• [tool.pyright]: https://github.com/microsoft/pyright/blob/main/docs/configuration.md (TypeScript)
• [tool.tombi]: https://tombi-toml.github.io/tombi/docs/configuration/ (Rust)
• [tool.rumdl]: https://github.com/rvben/rumdl (Rust)

Other tools are considering adding support:

• Support for pyproject.toml (and cargo.toml) lycheeverse/lychee#1930 (Rust)
• https://github.com/orgs/zizmorcore/discussions/322#discussioncomment-15919620 (Rust)
• Support taplo configuration in pyproject.toml tamasfe/taplo#603 (Rust)
• Support configuration in [tool.actionlint] section of pyproject.toml rhysd/actionlint#623 (Go)
• Support configuration in [tool.shfmt] section of pyproject.toml mvdan/sh#1268 (Go)
• Support configuration from pyproject.toml gitleaks/gitleaks#2066 (Go)
