chore: add github action for golang

[haunt98]

• [x] Remove .travis.yml
• [x] Use latest go version 1.15.x as possible
• [x] Use golangci-lint version 1.28
• [x] Use Ubuntu 20.04 for testing and linting
• [x] Test building on Windows, MacOS

You can see github action running in my fork: https://github.com/haunt98/go-mod-upgrade/actions/runs/679138635

Hi,

Thanks for your contribution.

We currently use Travis as our CI/CD, so to completely migrate to Github Actions, we should:

• remove the file .travis.yml
• use go version 1.15.x in .github/workflows/go.yaml, as Go version 1.15 is our minimum supported version
• use golangci-lint version 1.28.0 in .github/workflows/go.yaml, as that's the version we use in the Makefile (maybe we could also update to the current latest version, v1.38.0)
• use Ubuntu 20.04 instead of latest in .github/workflows/go.yaml, as latest can change in time
• we could also test the build on Windows and Mac OS (if it's available in Github Actions ?)
