Syntax error in alert.twig: Missing closing div tag and duplicate endfor

The components/alert/alert.twig template contains a Twig syntax error that causes the error:

Twig\Error\SyntaxError: Unknown "endfor" tag in "bootstrap_barrio:alert" at line 79.

Steps to reproduce:
1. Use Bootstrap Barrio 5.5.x
2. Trigger a status message/alert
3. Observe Twig syntax error

Root cause:
In commit 7e4e4a8 (Issue #3485305), when removing the close button from the alert template, the closing

tag was also accidentally removed and replaced with a duplicate {% endfor %} tag.

The template has two {% for %} loops:
• Outer loop at line 32: {% for type, messages in message_list %}
• Inner loop at line 69: {% for message in messages %}

But there are three {% endfor %} tags:
• Line 76: closes inner loop (correct)
• Line 79: duplicate/extra (incorrect - should be < /div> (added a space to have this render in the description))
• Line 80: closes outer loop (correct)

Additionally, the

closing tag at line 78 to close the div opened at line 55.
