chore: Move from TavisCI to GitHub Actions (#783)

* format code

* Create GH Actions workflow based on previous Travis setup

* Only from master

Was just temporarily enable for other branches for testing

* Remove obsolete Travis config

* Base semantic-release action off of dom-testing-library

https://github.com/testing-library/dom-testing-library/blob/74c63b7be5c7d628e3a415396bc6f3d83a90c28e/.github/workflows/validate.yml#L57-L99

* Complete full matrix

* Remove unnecessary secrets usage from dry run

* We need secrets being set

See https://semantic-release.gitbook.io/semantic-release/usage/configuration#dryrun:
"Note: The Dry-run mode verifies the repository push permission, even though nothing will be pushed. The verification is done to help user to figure out potential configuration issues."
