Add noqa_row to diagnostics JSON format (#3228)

In ruff-lsp (https://github.com/charliermarsh/ruff-lsp/pull/76) we want to add a "Disable \<rule\> for this line" quickfix. However, finding the correct line into which the `noqa` comment should be inserted is non-trivial (multi-line strings for example).

Ruff already has this info, so expose it in the JSON output for use by ruff-lsp.
