Usability issue: "Your branch is up to date"

[Manuel Quiñones <manuel.por.aca@xxxxxxxxx>]

Hi,
I've been teaching Git to a group of young learners lately. They find
it odd that commands like `git status` or `git switch main` say "Your
branch is up to date with 'origin/main'" even when there are changes
that can be fetched from the remote. My proposal: Add the timestamp of
the last fetch to the message. For example:

```
$ git switch main
Switched to branch 'main'
Your branch is up to date with 'origin/main'. Last check was 2 hours ago.
```

It looks like the timestamp of file `.git/FETCH_HEAD` would be enough
to implement it.
