BUG: pd.to_csv(..., compression="zip") creates multiple files in zip archive that cannot be read by pd.read_csv()
- [x] I have checked that this issue has not already been reported.

- [x] I have confirmed this bug exists on the latest version of pandas.

- [ ] (optional) I have confirmed this bug exists on the master branch of pandas.

#### Code Sample, a copy-pastable example

```python
import pandas as pd

# enough data to cause chunking into multiple files
n_data = 100000
df = pd.DataFrame(
    {'name': ["Raphael"]*n_data,
    'mask': ["red"]*n_data,
    'weapon': ["sai"]*n_data,
    }
)

compression_opts = dict(method='zip', archive_name='out.csv')
df.to_csv('out.csv.zip', index=False, compression=compression_opts)

# reading back the data produces an error
r_df = pd.read_csv("out.csv.zip")

# passing in compression_opts doesn't work either
r_df = pd.read_csv("out.csv.zip", compression=compression_opts)
```

How pandas was installed:

```bash
~/projects/testing$ ~/.pyenv/versions/3.8.6/bin/python3.8 -m venv text_venv
~/projects/testing$ . text_venv/bin/activate
(text_venv) ~/projects/testing$ pip install pandas==1.2.0
```

#### Problem description

Introduced in 1.2.0, `to_csv` with compression="zip" has an issue with chunking of data into multiple data files within the zip archive, when reading back the data this produces an error. When the data is very small (for example if `n_data` above was 2), this produces only one data file in the archive and no error when reading the archive.

This has been reported by other users on StackOverflow here: https://stackoverflow.com/questions/65689941/when-using-pandas-dataframe-to-csv-with-compression-zip-it-creates-a-zip-f

#### Expected Output

The `to_csv` should work with `read_csv` using zip compression. The behaviour with small data and medium sized data should be the same. The archive should always contain a single file or be read into a single df.

#### Output of ``pd.show_versions()``
