[Feature Request] Option to Toggle List Type

Hi! Thank you for your work on this library, I just implemented it in the next version of my personal website/blog to generate a TOC for my blog posts since my previous library of choice was coupled to the Gatsby/Remark ecosystem.

I wanted to utilize un-ordered list instead of ordered list for my use case, but it did not appear there was a built-in option to change this and it required writing a custom pre-parser to change the tagType in the HAST before generating the HTML. I think this is a pretty straight forward use case that would be valuable as an optional toggle value in the library options.

Would you be open to this change? I am happy to create a PR to add this functionality if so.

It seems that this guy figured it out here #6 ... but failed to share his technique.

Maybe if we all chastise him vehemently he will share the answer ;)

just use css like this:

 .toc .toc-item::marker {
    font-size: 0px;
 }

To make it dot:

.toc .toc-item::marker {
  content: '·';
  font-weight: bold;
}

use customizeTOC option.

const convertTocOlToUl = (node) => {
  if (!node) return node;
  if (node.tagName === 'ol') {
    node.tagName = 'ul';
  }
  node.children?.forEach((item) => {
    if (item.tagName === 'ol') {
      item.tagName = 'ul';
    }
    if (item.children) {
      item = convertTocOlToUl(item);
    }
  });

  return node;
};

use(rehypeToc, {
  customizeTOC: (node) => {
    return convertTocOlToUl(node);
  },
})

result

another option is just do it in css:

          '& nav ol': {
            listStyleType: 'disc',
          },
