"short" Welcome Banner option (#14638)
# Description

Adds:

```nushell
$env.config.show_banner = "short"
```

This will display *only* the startup time. That was the only information
from the banner that the user couldn't possibly include in their own
config/banner (since it is `-1ns` during startup). This allows one to
create their own banner and yet still show the startup time.

Example (can be a file named `banner.nu` in autoloads:

```nushell
$env.config.show_banner = "short"

let ver = (version)
print $"(ansi blue_bold)Nushell Release:(ansi reset) ($ver.version) \(($ver.build_os)\)"
```

`true` and `false` settings continue to work as they do today. `true` is
still the default.
