Fix Option<&str> == Option<&String> w/ rust_decimal/rkyv feat (#11205)

Browse source 
Without this change, projects which depend on both nu-command and
rust_decimal's "rkyv" feature cause nu-command to fail to compile.

```toml
[dependencies]
nu-command = { path = "../nushell/crates/nu-command" }
rust_decimal = { version = "1", features = ["rkyv"] }
```

```console
error[E0277]: can't compare `std::option::Option<&str>` with `std::option::Option<&std::string::String>`
   --> nushell/crates/nu-command/src/filters/join.rs:367:35

              <std::option::Option<U> as PartialEq<rkyv::option::ArchivedOption<T>>>
