Update parquet-go dependency to parquet-go/parquet-go

[stoewer]

The repository segmentio/parquet-go has been archived. The active development of the library was moved to the new parquet-go GH organization.

The parquet-go dependency and import paths should be updated to the github.com/parquet-go/parquet-go package.

Update: I verified that all Tempo tests pass on the new dependency and benchmarks are +/- a few %. We should target this after releasing 2.2.
