FINERACT-2335: don't rename release tarballs

Release tarballs are currently renamed (without changing the contents): apache-fineract-src-1.12.1.tar.gz becomes apache-fineract-1.12.1-src.tar.gz . The former matches the exploded directory name, the latter does not. The difference is subtle but meaningful... I strongly prefer the former because it's less surprising / more common, and easier to work with from scripts.

There's no functional difference, this should only impact aesthetics.

I did also shorten `binary` to `bin` so release artifact name lengths match.
