program publish script

Problem

We have publish scripts for the clients, but no such script for the program.

Summary of Changes

Add publish scripts for the program! Taken directly from the Rust client publishing pipeline.

Note I'll have to revert #22 and use the new pipeline to publish the release. The crate was never published.

To be honest, I think having multiple copies of the same scripts (mostly) is pretty error-prone -- can we parametrize the inputs and just reuse the same script?

The SPL version of the publish script takes a path to the package to publish so we don't need a script for every package in the repo: https://github.com/solana-labs/solana-program-library/blob/master/.github/workflows/publish-rust.yml

@joncinque Agreed, let's move to shared scripts. @lorisleiva said he and @febo are working on this over in System Interface land, so whenever that's all done we can export those changes here and get a shared script for all of these operations for Rust crates.
