add any -> record to metadata (#9755)
# Description
in the help page of `metadata`, there is the following example
```nushell
ls | metadata
```
which gives the following error
```
Error: nu::parser::input_type_mismatch

  × Command does not support table input.
   ╭─[entry #2:1:1]
 1 │ ls | metadata
   ·      ────┬───
   ·          ╰── command doesn't support table input
   ╰────
```

this PR adds `any -> record` to the signatures of `metadata` to allow
the use of that kind of example.
