Port to GitHub Actions

[XAMPPRocky]

Hello, would it be possible to port trust to GitHub Actions? Either as an alternative or replacing the current scripts. It would be nice for downstream repositories to be able to transition to GitHub Actions and maintain the same platform compatibility.

This would be very useful. Might be a good fit for the Rust CLI book per https://github.com/rust-lang-nursery/cli-wg/issues/153

This feature is increasingly interesting now when the future of Travis CI seems to become a quite expensive, subscription based, choice for CI.

@EmilSodergren You might be interested in the GitHub action template I made for Tokei's CI to replace trust. https://github.com/XAMPPRocky/mean-bean-ci-template

I use cross and the GitHub CLI in GitHub Actions workflows. Example: https://github.com/open-contracting/cardinal-rs/blob/main/.github/workflows/release.yml
