list, record and table type signatures were mentioned in several places, but never discussed in detail. The recently added oneof type declaration wasn't documented anywhere (except in the blog post introducing nu 0.105.0, where it was added). Add sections for list, record, table and oneof compound types to the Language Reference Guide. Add a link to the relevant reference page in the "Custom Commands"/"Parameters"/"Parameter Types" section of the book.

In the current version of nushell, {} | first_key returns an empty result instead of producing a runtime error.
