DOC: Update doc of parquet compression parameter

[ChristofKaufmann]

This commit updates the interface documentation of pandas.DataFrame.to_parquet. The documentation of the parameter compression is not up-to-date compared to the implementation documentation of pandas.io.parquet.to_parquet. This commit copies the documentation of the implementation to the interface.

Could you merge in the main branch? Appears to be a linting error as well.

[ChristofKaufmann]

Yes, now it has. It says "pandas/core/frame.py:2804:89: E501 Line too long (91 > 88 characters)". It refers to the line, where you requested to add the default value to get a consistent style. However, this is why the first line of this parameter description exceeds the maximum line width.

• We could move the default value back to the second line.
• We could replace the list of possible values by str or None, default 'snappy'. The text still describes possible values.
• We could ignore the failing check or somehow add an expected failure.
• You could extend the allowed line width.

What do you think is the best fix?

This option sounds best

[ChristofKaufmann]

Should be fine now.
