replace travis CI with github actions (check syntax, check links)

- travis CI free plans were discontinued
- CI pipeline is similar to https://github.com/awesome-selfhosted/awesome-selfhosted-data and uses https://github.com/nodiscc/hecat
- the pipeline will not pass until https://github.com/awesome-foss/awesome-sysadmin/issues/416 has been fixed
- ref. https://github.com/awesome-foss/awesome-sysadmin/issues/405
