`read_json` accepts a list of paths at runtime but the type stub only allows a single path.

What happens?

Hi duckdb team, big fan of the product!

I'm experiencing a small typing issue:

import duckdb

con = duckdb.connect()
rel = con.read_json(
    ["a.jsonl", "b.jsonl"],
    format="newline_delimited",
)
print(rel.count("*").fetchone())

This runs fine and returns the union of both files.

However, pyright throws:
Argument of type "list[str]" cannot be assigned to parameter "path_or_buffer" of type "str | bytes | PathLike[str] | PathLike[bytes] | IO[bytes] | IO[str]"

mypy throws a similar error.

Adding list[str] (and probably list[PathLike]) to path_or_buffer in the Python stub would fix this

To Reproduce

import duckdb

con = duckdb.connect()
rel = con.read_json(
    ["a.jsonl", "b.jsonl"],
    format="newline_delimited",
)
print(rel.count("*").fetchone())
