function hook_language_switch_links_alter

A language switcher link may need to point to a different path or use a translated link text before going through the link generator, which will just handle the path aliases.

Parameters

array $links: Nested array of links keyed by language code.

string $type: The language type the links will switch.

\Drupal\Core\Url $url: The URL the switch links will be relative to.
