Update auth.php and theme_handler.php to us ea bootstrap 5 admin theme and comply to use BS5 as it should.

[Alex-e107nl]

Motivation and Context

Without it you cannot use the bootstrap5 theme as admin theme and the tabs in the theme config (front and admin) does not give real tabs.

Description

admin/auth.php

if($adminTheme !== 'bootstrap3'/* && $adminTheme !== 'bootstrap5'*/) to
if($adminTheme !== 'bootstrap3' && $adminTheme !== 'bootstrap5')

theme_handler.php

<li class='active'><a data-toggle='tab' data-bs-toggle='tab' href='#core-thememanager-configure'>".LAN_CONFIGURE."</a></li>";
To
<li class='nav-item active'><a class='nav-link active' data-toggle='tab' data-bs-toggle='tab' href='#core-thememanager-configure'>".LAN_CONFIGURE."</a></li>";

$text .= "<li><a data-toggle='tab' data-bs-toggle='tab' href='#core-thememanager-customconfig'>".LAN_PREFS."</a></li>\n";
To
$text .= "<li class='nav-item'><a class='nav-link' data-toggle='tab' data-bs-toggle='tab' href='#core-thememanager-customconfig'>".LAN_PREFS."</a></li>\n";

text .= "<li><a data-toggle='tab' data-bs-toggle='tab' href='#core-thememanager-help'>".LAN_HELP."</a></li>\n";
