shells/nushell: update to 0.38.0

Today, we're releasing 0.38 of Nu. This release includes polish to the user
interface, improvements to how columns are passed, lots of bug fixes, and
updates on the upcoming engine.

What's New
-Quickly jump to a shell (tw4452852)
If you've used shells, you've no doubt used the n and p commands to quickly jump
between them. This can be a big time saver when you're working in multiple
directories.

In this release, we've added a g command that helps you quickly jump to a
particular shell. This helps in the cases where you end up with more than two
shells open and you already know what shell you want to jump to.
