fix: support text for * transformer

[jannes-mingram-lendi]

Allow text option for * transformer

There seems to be a bug where the text option doesn't work with the "any-tag" option:

const clean = sanitizeHtml("<p>Hello</p>", {
  transformTags: {
    'p': function(tagName, attribs) {
      return {
        tagName: 'p',
        text: 'Some text'
      };
    }
  }
});
// <p>Some text</p>

const clean = sanitizeHtml("<p>Hello</p>", {
  transformTags: {
    '*': function(tagName, attribs) {
      return {
        tagName: tagName,
        text: 'Some text'
      };
    }
  }
});
// expected: <p>Some text</p>
// actual: <p>Hello</p>
