No support for .prettierrc.mjs

[Swivelgames]

My project uses .prettierrc.mjs for it's rc file, but it doesn't appear to be getting used by coc-prettier. When I format a document in VIM, it's markedly different than when running prettier from the console.

/** @type {import("prettier").Config} **/
const config = {
	arrowParens: "avoid",
	endOfLine: "lf",
	printWidth: 100,
	trailingComma: "all",
	useTabs: true,
};

export default config;

This is because coc-prettier is on prettier 2.6.2. Support for esm module config files wasn't added until 3.0 https://prettier.io/blog/2023/07/05/3.0.0.html#api.
