Bump github actions checkout to v4

[sanders41]

Pull Request

GitHub Actions are currently failing across multiple repositories with network issues. the checkout action is currently having issues with this, issue here, and bumping to the newly released v4 seems to be helping. This action is not the only thing that is having issues with the network problems so we could still see failures until it is resolved, but bumping to v4 is at least helping with the checkout part.

These network issues are also what keep causing #839 to fail.
