add to ndjson and to jsonl to the standard library (#10519)
follow up to
- #10283

# Description
even though it appears defining `to foo` does not allow to do `save
x.foo` for free (see https://github.com/nushell/nushell/issues/10429),
because #10283 did add `from ndjson` and `from jsonl` to the standard
library, i thought adding their `to ...` counterpart would make sense
😋

# User-Facing Changes
users can now convert structured data back to NDJSON and JSONL 👌

# Tests + Formatting
this PR adds the exact same tests as for the `from ...` commands
- structured data is in `result` and the string is now the expected
- the two invalid `from ...` tests cannot be reproduced for `to ...`
afaik
