Description

Related to ARROW-17072

As noted in the following document, the recommended extension for IPC files is now `.arrow`.

> We recommend the “.arrow” extension for files created with this format.
https://arrow.apache.org/docs/format/Columnar.html#ipc-file-format

However, currently when writing a dataset with the write_dataset function, the default extension is .feather when feather is selected as the format, and .ipc when ipc is selected.
