Tweak: maybe add the same capability check (manage_settings) also for js as menu icon

[geckod22]

Proposed changes

the module does this two calls:

	add_action( 'admin_init', array( $this, 'register_assets' ) );
	add_action( 'admin_bar_menu', array( $this, 'newfold_help_center' ), 11 );

the menu icon is showed if:
current_user_can( 'manage_options' )
&& is_admin()
&& $this->container->get( 'capabilities' )->get( 'canAccessHelpCenter' )

while the css and js are loaded if:
file_exists( $asset_file )
&& $this->container->get( 'capabilities' )->get( 'canAccessHelpCenter' )

so what happens is that if I have a contributor role and access the admin dashboard, I do not see the help center icon in topbar as I do not have the manage_options but the css and js are still loaded - I think we should avoid this but I am not sure the js is loaded to make the functions available to a third part thing
