TST: add test to read binary jsonlines in chunks

[Alvaro-Kothe]

• closes read_json doesn't work on binary files with lines=True and chunksize #28906 (Replace xxxx with the GitHub issue number)
• Tests added and passed if fixing a bug or adding a new feature
• All code checks passed.
• Added type annotations to new arguments/methods/functions.
• Added an entry in the latest doc/source/whatsnew/vX.X.X.rst file if fixing a bug or adding a new feature.
• If I used AI to develop this pull request, I prompted it to follow AGENTS.md.

I adapted the test from this PR to Python 3.7 in commit d378852.

@pytest.mark.parametrize("chunksize", [1, 1.0])
@pytest.mark.parametrize("buffer", [BytesIO, StringIO])
def test_readjson_chunks(request, lines_json_df, chunksize, buffer):
    # Basic test that read_json(chunks=True) gives the same result as
    # read_json(chunks=False)
    # GH17048: memory usage when lines=True
    # GH#28906: read binary json lines in chunks

    if buffer == BytesIO:
        lines_json_df = lines_json_df.encode()

    unchunked = read_json(StringIO(lines_json_df), lines=True)
    with buffer(lines_json_df) as buf:
        reader = read_json(buf, lines=True, chunksize=chunksize)
        chunked = pd.concat(reader)

    tm.assert_frame_equal(chunked, unchunked)

Here is the test summary:

$ pytest pandas/tests/io/json/test_readlines.py::test_readjson_chunks -v

=========================== 2 failed, 2 passed, 8 warnings in 0.30s ===========================

The error only occorred when using a context manager.
