Migrate from Travis to GitHub Actions

[syntaqx]

Provide multiple asynchronous workflows to replace the CI & CD that's currently provided by Travis:

• [ ] go test
• [ ] go modules && verification
• [ ] golangci-lint
• [ ] goreleaser

Don't forget to remove .travis.yml and update the readme shield

Hi, can I try this sir? I successfully migrate the lint and test parts but need a review for codecov setting. Thank you.
