fix: larger exit column width on Windows (#3119)

The default width of the `exit` column is 3, which matches the 0-255
values on Linux. However, on Windows it is a 32-bit integer, and can be
anything from -2147483648 to 2147483647. Popular tools such as `winget`
apparently make use of that.

Here's an example with `columns = ["exit", "time", "duration",
"directory", "command"]`:

/>


This PR changes the default column width to 11 on Windows to match these
values. The result is:

<img width="601" height="412" alt="image"
