Title attribute removed from site-name link in SystemBrandingBlock

The site-name link in the Site Branding block template previously had a title attribute which was inaccessible to many groups of users. This attribute has been removed from all copies of block--system-branding-block.html.twig in the Drupal core.

Before:

{% if site_name %}
  <a href="{{ path('<front>') }}" title="{{ 'Home'|t }}" rel="home">{{ site_name }}</a>
{% endif %}

After:

{% if site_name %}
  <a href="{{ path('<front>') }}" rel="home">{{ site_name }}</a>
{% endif %}
