GH actions support

to some extent we have this via quickinstall, but it'd be pretty neat to have a cargo-binstall action that takes a list of packages to install (or uses Tools.toml per #176) for CI environments, especially if we can make caching easy for any compiled tools because that's always been a pain point in CI.

It might be worth it to have our own dedicated and maintained action, but this is essentially what https://github.com/taiki-e/install-action does. We could recommend using that in the readme, for now?

I second this, and I really don't think it's worth the effort to create another one.

The other side of the equation, but I feel like there's a couple of gh actions that would be very useful:

1. a tool and an action to lint a Cargo.toml for the binstall metadata syntax
2. a gh action to package a crate ready for upload to a release, defaulting to binstall's zero-config format
   • we could also read the Cargo.toml metadata and use the format defined there, if present
   • it won't cover very specialised cases, but i feel if we provide a turnkey solution for the 90% it would get many projects going
   • when we do signing we could then have a straightforward path to enable signatures for the entire userbase at once

oh neat! yeah let's do that

We've had our own gh action for a while now. Closing.
