Remove tab index from Altis link

[robindevitt]

Originally reported in #629

tabindex="0" is redundant, as links already get keyboard focus by nature.

Code for reference:

altis-cms/inc/branding/namespace.php

Lines 232 to 245 in 46312bf

	function admin_bar_menu( WP_Admin_Bar $wp_admin_bar ) {
	$logo_menu_args = [
	'href' => admin_url(),
	'id' => 'altis',
	'title' => '<span class="altis-logo-wrapper"><img src="' . get_logo_url( 'white' ) . '" alt="Altis Admin" /></span>',
	];
	// Set tabindex="0" to make sub menus accessible when no URL is available.
	$logo_menu_args['meta'] = [
	'tabindex' => 0,
	];
	$wp_admin_bar->add_menu( $logo_menu_args );
	}

Suggested change is to remove lines 239 - 240

altis-cms/inc/branding/namespace.php

Lines 239 to 242 in 46312bf

	// Set tabindex="0" to make sub menus accessible when no URL is available.
	$logo_menu_args['meta'] = [
	'tabindex' => 0,
	];
