std::fmt: Use args directly in example code
The lint "clippy::uninlined_format_args" recommends inline variables in format strings. Fix two places in the docs that do not do this. I noticed this because I copy/pasted one example in to my project, then noticed this lint error. This fixes:
```
error: variables can be used directly in the `format!` string
--> src/main.rs:30:22
|
30 | let string = format!("{:.*}", decimals, magnitude);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
error: variables can be used directly in the `format!` string
--> src/main.rs:39:2
|
39 | write!(&mut io::stdout(), "{}", args).unwrap();
```
