Rollup merge of #136347 - allevo:patch-1, r=Amanieu
Add a bullet point to `std::fs::copy`
I needed to copy a file but I got the following error:
```
Os { code: 2, kind: NotFound, message: "No such file or directory" }
```
After read the documentation, I though the error was generated by the `from` parameter, forgetting the `to` part. Anyway, I got the error because the parent folder of `to` didn't exist.
Even if the documentation explicitly saying `but is not limited to just these cases`, I would like to add this case because I spent 3 hours around it.
This PR just wants to put a mention about it.
