Bug 2069193 - Move the ruff-format exclusions to format.exclude. r=linter-reviewers,sergesanspaille

Unlike the yaml list, which mozlint applied before invoking the formatter,
these are resolved by ruff against the project root, so they no longer depend
on the directory `mach lint` happens to be run from.
