Add last update date

[NeverSm1le]

Would you consider adding a "last updated" line to each console in https://www.copetti.org/writings/consoles/? The "recently updated" section only have 3 entries so it's kinda impossible to keep track of what console is updated from the last read

It's a good idea, I'll study a way to show this without overloading the current design.
