[SPARK-39240][INFRA][BUILD] Source and binary releases using differen…

…t tool to generate hashes for integrity

### What changes were proposed in this pull request?

unify the hash generator for release files.

### Why are the changes needed?

Currently, we use `shasum` for source but `gpg` for binary, since apache#30123

this confuses me when validating the integrities of spark 3.3.0 RC https://dist.apache.org/repos/dist/dev/spark/v3.3.0-rc2-bin/

### Does this PR introduce _any_ user-facing change?

no

### How was this patch tested?

test script manually

Closes apache#36619 from yaooqinn/SPARK-39240.
