open: Assign content_type metadata for filetypes not handled with a from converter (#14670)
# Description

Filetypes which are converted during `open` should not have (and have
not had) a `content_type` metadata field. However, filetypes which
aren't converted now behave the same as with `--raw` and assign the
appropriate `content_type`.

## Before

```nushell
open toolkit.nu | metadata
# => ╭────────┬────────────────────────────────────────────╮
# => │ source │ /home/ntd/src/ntd-forks/nushell/toolkit.nu │
# => ╰────────┴────────────────────────────────────────────

open --raw toolkit.nu | metadata
# => ╭──────────────┬────────────────────────────────────────────╮
# => │ source       │ /home/ntd/src/ntd-forks/nushell/toolkit.nu │
# => │ content_type │ application/x-nuscript                     │
# => ╰──────────────┴────────────────────────────────────────────╯

open script.py | metadata
# => ╭────────┬─────────────────────────────╮
# => │ source │ /home/ntd/testing/script.py │
# => ╰────────┴─────────────────────────────╯

open Cargo.toml | metadata
# => ╭────────┬────────────────────────────────────────────╮
# => │ source │ /home/ntd/src/ntd-forks/nushell/Cargo.toml │
# => ╰────────┴────────────────────────────────────────────╯
```

## After

```nushell
# Not converted, so adds content_type
open toolkit.nu | metadata
# => ╭──────────────┬────────────────────────────────────────────╮
# => │ source       │ /home/ntd/src/ntd-forks/nushell/toolkit.nu │
# => │ content_type │ application/x-nuscript                     │
# => ╰──────────────┴────────────────────────────────────────────╯

# Not converted, so adds content_type
open --raw toolkit.nu | metadata
# => ╭──────────────┬────────────────────────────────────────────╮
# => │ source       │ /home/ntd/src/ntd-forks/nushell/toolkit.nu │
# => │ content_type │ application/x-nuscript                     │
# => ╰──────────────┴────────────────────────────────────────────╯

# Not converted, so adds content_type
open script.py | metadata
# => ╭──────────────┬─────────────────────────────╮
# => │ source       │ /home/ntd/testing/script.py │
# => │ content_type │ text/plain                  │
# => ╰──────────────┴─────────────────────────────

# Converted, so does not add content_type (no change)
open Cargo.toml | metadata
# => ╭────────┬────────────────────────────────────────────╮
# => │ source │ /home/ntd/src/ntd-forks/nushell/Cargo.toml │
# => ╰────────┴────────────────────────────────────────────╯
```

# User-Facing Changes

`open <file>` assigns the appropriate content type when the filetype is
not converted via a `from <format>`.

# Tests + Formatting

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
