Update description and error types for split-by (#10865)
# Description

`split-by` only works on a `Record`, the error type was updated to
match, and now uses a more-specific type. (Two type fixes for the price
of one!)

The `usage` was updated to say "record" as well

# User-Facing Changes

* Providing the wrong type to `split-by` now gives an error messages
with the correct required input type

Previously:

```
❯ ls | get name | split-by type
Error:   × unsupported input
   ╭─[entry #267:1:1]
 1 │ ls | get name | split-by type
   ·      ─┬─
   ·       ╰── requires a table with one row for splitting
   ╰────
```

With this PR:

```
❯ ls | get name | split-by type
Error: nu:🐚:type_mismatch

  × Type mismatch.
   ╭─[entry #1:1:1]
 1 │ ls | get name | split-by type
   ·      ─┬─
   ·       ╰── requires a record to split
   ╰────
```
