/**
 * Generate a list of contributors.
 *
 * In short, this plugin:
 *
 * * looks for the first heading matching `/^contributors$/i` or
 *   `options.heading`
 * * if no heading is found and `appendIfMissing` is set, injects such a
 *   heading
 * * if there is a heading, replaces everything in that section with a new
 *   table
 *
 * ##### Notes
 *
 * * define fields other than `name`, `url`, `github`, or `twitter` in
 *   `formatters` to label them properly
 * * by default, fields named `url` will be labelled `Website` (so that
 *   `package.json` contributors field is displayed nicely)
 * * by default, fields named `email` are ignored
 * * name fields are displayed as strong
 * * GitHub and Twitter URLs are automatically stripped and displayed with
 *   `@mention`s wrapped in an `https://` link
 * * if a field is undefined for a given contributor, then the value will be an
 *   empty table cell
 * * columns are sorted in the order they are defined (first defined means
 *   first displayed)
 *
 * @param {Readonly<Options> | null | undefined} [options]
 *   Configuration (optional).
 * @returns
 *   Transform.
