Fixed wrong package name in examples

[Xuanwo]

warning: skipping duplicate package `parquet_write_parallel` found at `/home/xuanwo/.cargo/git/checkouts/arrow2-6249446b5f8db6f7/6608071/examples/parquet_write_parallel`

This PR fixes it.

Clippy seems wrong in CI, should I fix this PR or start a new one?

[jorgecarleitao]

Thank you for this PR 🙇 yeah, 1.62 landed with new clippy warnings. As you prefer - if you can that would be awesome, otherwise we merge it - main is broken anyway with the new clippy.
