Description

With #2846 being merged since a few releases, I think it is time to consider whether or not the "guidelines" field should be exposed by the NPM package (beyond it being present in the _data/simple-icons.json file).

That is, in terms of the Node Usage section of the README:

  const simpleIcons = require('simple-icons');

  console.log(simpleIcons.get('Simple Icons'));

  /*
  {
      title: 'Simple Icons',
      slug: 'simpleicons',
      hex: '111111',
      source: 'https://simpleicons.org/',
+     guidelines: '[THE GUIDELINES URL]' or ???, 
      svg: '<svg role="img" viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">...</svg>',
      path: 'M12 12v-1.5c-2.484 ...'
  }
  */

The main question being - if we decide to include this field - what its value should be if there are no guidelines for a brand. I think we are fine if the field is omitted, but that may be too shortsighted 🙃

Small remark I want to add here: this would require us to update the DefinitelyTyped types for simple-icons.
