DOC: DataFrame.reset_index names param can't be a tuple as docs state
- [ ] closes #57994
- [ ] All [code checks passed](https://pandas.pydata.org/pandas-docs/dev/development/contributing_codebase.html#pre-commit).

Hi, I am new to open source and this is my first PR. I'm not sure why the build is failing, can I get some help? I think there was a temporary network problem that caused the checks to fail.

The PR looks good to me, thanks. Thanks @gboeker
