Fix test for Apache Parquet files for file 5.47

The output for Parquet files changed in 5.47. This commit edits the test
to accept both the old and new output.

```sh
# Old
$ file example.parquet
example.parquet: Apache Parquet
$ file --mime example.parquet
example.parquet: application/octet-stream; charset=binary

# New
$ file example.parquet
example.parquet: Apache Parquet file
$ file --mime example.parquet
example.parquet: application/vnd.apache.parquet; charset=binary
```
