Allow GitHub Actions badges in the badges section #8076
Description
Allow github action badges to be included in the [badges] section of Cargo.toml
Currently, the badges section of Cargo.toml supports Appveyor, CircleCI, Cirrus CI, GitLab, Azure DevOps, Travis CI, and Bitbucket Pipelines.
Gihub has made their Actions available for all public github repositories. And, with actions-rs, it is very easy to add tests and builds to the github workflow. They generate badges that could be accepted by Cargo.toml and crates.io
