Allow for .parq file ending as alternative to .parquet (#10112)

# Description

Many systems like Hadoops HDFS store parquet files with the short
variant `.parq`. It is quite annoying to rename these file before
opening them with nushell. This PR lets nushell accept .parq alongside
.parquet file endings.
