Change behaibour of command /checkupdate

[Antroxin]

First of all, thank you for the bot and the good work made.

When /checkupdate command is selected, it offers the list of installed dockers so user has to press the docker to update but there is no info about what dockers have a new version avaiable.

My sugestion is to add some mark or colour to notice that a new version is available to update the docker in the list.

Hello!

In fact right now you can find out if a container needs an update from the /list command. You'll see a ⬆️ emoji.
(Not in the buttons)

To perform the update you can do it from /checkupdate and from /info.

Regards

Edit: adding screenshots

If you use the /info command

If you use /checkupdate command

I preferred not to indicate it on the buttons because there is not enough space to show the entire name of the container... If I add one more icon, less space.

Finally I will change the status icons for ✔️ and ⬆️ icon in this command.
