SQL-style join command for Nushell tables (#8424)
This PR adds a command `join` for performing SQL-style joins on Nushell
tables:

```
〉join -h
Join two tables

Usage:
  > join {flags} <right-table> <left-on> (right-on)

Flags:
  -h, --help - Display the help message for this command
  -i, --inner - Inner join (default)
  -l, --left - Left-outer join
  -r, --right - Right-outer join
  -o, --outer - Outer join

Signatures:
  <table> | join list<any>, <string>, <string?> -> <table>

Parameters:
  right-table <list<any>>: The right table in the join
  left-on <string>: Name of column in input (left) table to join on
  (optional) right-on <string>: Name of column in right table to join on. Defaults to same column as left table.

Examples:
  Join two tables
  > [{a: 1 b: 2}] | join [{a: 1 c: 3}] a
  ╭───┬───┬───╮
  │ a │ b │ c │
  ├───┼───┼───┤
  │ 1 │ 2 │ 3 │
  ╰───┴───┴───╯
```
