[Feature Request]: Last Time Played

[Kody-Schram]

Checklist

• I have searched for a similar issue in this repository and did not find one.

Description

Store the last time played for each game in play_time.txt

Reason

Simple quality of life feature so users can see when they last played a game.

Examples

RPCS3 also stores this information

Since playtime is already stored in play_time.txt, just appending last time played for each game entry would make sense to me
