Automate publish to crates.io

[spenserblack]

This is pretty much just copied and pasted from here.

I thought we were doing this already, but a quick search on cs.github.com didn't turn anything up.

As it doesn't use the existing file from make build (cargo publish always rebuilds AFAIK), I
made this a separate job.

Suggested change

	cargo-publish:
	name: Publish to crates.io
	runs-on: ubuntu-latest
	env:
	CARGO_TERM_COLOR: always
	steps:
	- uses: actions/checkout@v3
	- name: Install Rust
	uses: actions-rs/toolchain@v1
	with:
	toolchain: stable
	profile: minimal
	components: clippy
	- name: Publish to crates.io
	env:
	CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN }}
	run: cargo publish
	- name: Publish to crates.io
	if: matrix.os == 'ubuntu-latest'
	env:
	CARGO_REGISTRY_TOKEN: ${{ secrets.CARGO_REGISTRY_TOKEN }}
	run: cargo publish

Why not just make it a step like the others?

If it's a separate job it can run in parallel without waiting on other steps or making other steps wait on it. But I'm not too attached to making it a separate job, so if you prefer it as a step then 👍 from me. I'll be happy either way 😃

Thanks a lot @spenserblack
I'm also surprised we haven't thought about this before 😅

I created the action secret containing the crates.io API token. So we should be all set for the next release.
