Clickable URL escape sequence

I'm trying to print a URL that is clickable, but I couldn't manage to echo the escape sequences to make it work.

For example:
```just
start_mail:
echo ⚙️ {{CYAN}} Starting {{BOLD+INVERT}} mailhog {{NORMAL}}
podman-compose start mail
echo ✅ {{BLUE}}Mailhog console available on {{UNDERLINE}}http://127.0.0.1:8025/{{NORMAL}}
```

I've used `{{UNDERLINE}}` in this example.

This is what I'm trying to achieve: [How I Turned Terminal Output into Clickable Links](https://www.timsanteford.com/posts/how-i-turned-terminal-output-into-clickable-links/)
