allow into filesize to take tables as input / output (#9706)
# Description
i have the following command that should give a table of all the mounted
devices with information about their sizes, etc, etc... a glorified
output for the `df -h` command:
```nushell
def disk [] {
    df -h
      | str replace "Mounted on" "Mountpoint"
      | detect columns
      | rename filesystem size used avail used% mountpoint
      | into filesize size used avail
      | upsert used% {|it| 100 * (1 - $it.avail / $it.size)}
}
```

this should work given the first example of `into filesize`
```nushell
  Convert string to filesize in table
  > [[bytes]; ['5'] [3.2] [4] [2kb]] | into filesize bytes
```

## before this PR
it does not even parse
```nushell
Error: nu::parser::input_type_mismatch

  × Command does not support table input.
   ╭─[entry #1:5:1]
 5 │       | rename filesystem size used avail used% mountpoint
 6 │       | into filesize size used avail
   ·         ──────┬──────
   ·               ╰── command doesn't support table input
 7 │       | upsert used% {|it| 100 * (1 - $it.avail / $it.size)}
   ╰────
```

> **Note**
> this was working before the recent input / output type changes

## with this PR
it parses again and gives
```nushell
> disk | where mountpoint == "/" | into record
╭────────────┬───────────────────╮
│ filesystem │ /dev/sda2         │
│ size       │ 217.9 GiB         │
│ used       │ 158.3 GiB         │
│ avail      │ 48.4 GiB          │
│ used%      │ 77.77777777777779 │
│ mountpoint │ /                 │
╰────────────┴───────────────────╯
```

> **Note**
> the two following commands also work now and did not before the PR
> ```nushell
> ls | insert name_size {|it| $it.name | str length} | into filesize
name_size
> ```
> ```nushell
> [[device size]; ["/dev/sda1" 200] ["/dev/loop0" 50]] | into filesize
size
> ```

# User-Facing Changes
`into filesize` works back with tables and this effectively fixes the
doc.

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`

this PR gives a `result` back to the first table example to make sure it
works fine.
