DOC: Corrected file description in read_fwf()
- [ ] closes #xxxx
- [x] tests added / passed
- [x] passes `black pandas`
- [x] passes `git diff upstream/master -u -- "*.py" | flake8 --diff`
- [ ] whatsnew entry

Changing the name looks good, but can you please remove the link to Oracle? That document is not a spec or description of the format, it's a description of how to open fixed width files with Oracle Enterprise Data Quality, and I don't think we want to have that. It's ok to have no link if there is no good page to link to.

Thanks! @datapythonista Link removed. Can you merge? Needs to pass CI first. @TomAugspurger , @datapythonista CI Tests passed, please merge! @isantolin would be really appreciated if you could stop telling us when to merge. Thanks
