shells/nushell: update to 0.37.0

Today, we're releasing 0.37 of Nu. This release adds a new find function,
improvements to the current engine, and updates on the upcoming engine.

What's New
finding data in tables

In 0.37, you now have access to a new find command, which can help you quickly
look for data across all columns in a table.
You can still reach your system's find command using ^ by typing ^find.

Additional improvements
-fdncred added more support for ansi art, and more chars
-aminya removed shelling out in some cases where it's not needed
-jt made sys/ps/fetch/post core commands, moving them from plugins to internal
commands. This allows for future capability to have nushell download its own
extensions.
-andrasio began adding support for creating errors inside of nushell code,
extended tags to support basic command reflection
-lily-mara added into filesize
-tw4452852 added support to append when calling save
-Pantoshire improved errors when bash-style alias was mistakingly used
-tranzystorek-io did a lot of general code improvements
-kubouch did some fixes to paths and the source command
-elferherrera updated the prompt environment variable to PROMPT_COMMAND to show
that it is nushell code that gets run
