DOC: Update orc.py to say orc instead of parquet
Looks like the [filesystem implementation was initially copy pasted](https://github.com/pandas-dev/pandas/pull/51623/files#diff-dcfc078a101eee58a0d665a67ac19730f1e6b68d3bf7760ca8bbede2746a4c39R72) from the parquet one, and a few edits were missed to refer to orc instead.

Thanks @mjperrone  I appreciate the fast response!

I discovered this error while investigating this issue with the implementation. I would _really_ appreciate 👀 on that as well!
