DOC: read_fwf claims to support a [str] in the first argument

Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Documentation problem

read_fwf does not support a string type in the filepath_or_buffer argument.

Parameters:
filepath_or_buffer : str, path object, or file-like object
String, path object (implementing os.PathLike[str]), or file-like object implementing a text read() function.The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. A local file could be: file://localhost/path/to/table.csv.

Suggested fix for documentation

remove str/string from this parameter documentation

Are you saying that it doesn't support something like "/path/to/file" or it doesn't support something like "a,b,c\n1,2,3" (string containing the content). The first one (str containing a path) should work? The second one is not intended to work.
