Provide a built-in function to escape HTML

Hi!

In the HTML node to generate HTML templates, there is a warning for XSS attacks, which is great! However, n8n users have no built-in way to escape HTML characters (" ’ < > &) from incoming $json.

I think it would be a great idea to add this function:

function escapeHTML(str) {
    return str.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;').replace(/"/g, '&quot;').replace(/'/g, '&#39;');
}

to the built-in convenience functions for strings.

What do you think?

Thank you!
