feat: support .yaml and .js configuration files

[Jason3S]

Related to #847

cspell will search for the following configuration files:

       'package.json',
        'cspell.json',
        'cSpell.json',
        '.cspell.json',
        '.vscode/cspell.json',
        '.vscode/cSpell.json',
        '.vscode/.cspell.json',
        '.cSpell.json',
        'cspell.yaml',
        'cspell.yml',
        'cspell.js',
        'cspell.cjs',

Is this correct?

cspell.js:

"use strict";

module.exports = {
    version: "0.1",
    language: "en-GB",
    dictionaries: ["typescript"],
    ignorePaths: ["dist", "package-lock.json"],
    ignoreWords: ["..."]
};

It doesn't seem to work. When I run npx cspell --version, for example, there is no output while that file exists.
