Thanks, @joberthrogers18!

I've added two commits with small changes:

• Instead of splitting the path by ':', we check if menu.url starts with "http". This way we match both http and https with less code/nesting.
• Added the example for external links to theme.toml (same you added in config.toml) and the footer_menu example in the Mastering tabi posts.

Thanks again!
