fix(deps): update @textlint/ast-node-types and refactor types

[azu]

Make acceptable node loose.

It allow to pass sentence node to new StringSource(node).

import { split, TxtSentenceNode } from "sentence-splitter";
import { StringSource } from "../src/StringSource";
const results = split("Hello world. This is a test.");
const [sentence1, sentence2] = results.filter((r) => {
    return r.type === "Sentence";
}) as TxtSentenceNode[];
const source = new StringSource(sentence1).toString()

It is intentionally loose definition to accept sentences-splitter's node and unist node.
