Update hardcoded upgrade tool to 14.12.2 (vaadin#3826)

Update security.adoc (vaadin#3806)

In LobbyView constructor the following row was added after channels have been created { channels = new VirtualList<>(); } based on earlier instructions in web page
https://vaadin.com/docs/latest/getting-started/tutorial/flow/second-view

channels.setRenderer(new ComponentRenderer<>(this::createChannelComponent));


This row is missing from this security web page (https://vaadin.com/docs/latest/getting-started/tutorial/flow/security) from LobbyView constructor snippet when the constructor is modified with new additions. Someone could copy the whole code as is and then the links to different channels would stop working.
