Add a autolink field

[wvanderp]

I'm working on an extension that will render markdown to markdown.
Then you can use marked to lex the markdown, change things, and then write it back to markdown.

While I know that parsing is an inherently lossy process, some of the details can be preserved.

In this PR, I propose to indicate if a link was an autolink or a regular link.

In the future, I might have more of these PRs.

This PR also fixes an issue with the node test runner. I'm running node 20.x, which indicated no unit tests were found.
With the changed command, the unit test now runs again.

If you have any questions or need any changes, please let me know because I'm happy to help.

It looks like that change to the unit tests breaks in the latest version of node.

I think adding these Boolean parameters to tokens would be fine. We should try to add them all at once to prevent a bunch of releases.

One other option is to use the raw property to determine these properties. The raw property should always be the actual markdown that was used to create that token.

import { marked } from 'marked';

marked.lexer(`
[http://example.com](http://example.com)

http://example.com

[http://example.com][example]

[example]: http://example.com
`);

I'm going to close this as stale. If you would like to continue working on this feel free to get the tests passing and reopen this.
