chore(tooling): keep ruff format out of Markdown, allow 10 dataclass fields

ruff format restyles Python blocks inside Markdown, which silently rewrote
the ffmpeg sample in README-intel.md. Documentation is not ours to restyle,
so exclude *.md.

Raise pylint max-attributes to 10: TranscriptResult is a data model and its
eight fields are not a design smell.
