ci(github-action): use output generated by semantic-release to push d…

…ocker image

  ## what
  - use semantic-release plugin 'semantic-release-export-data' to store
    output in github actions whether a new version will be release ornot.
  - remove job 'extract-envs'
  - set NEXT_VERSION env depending if semantic-release will be released
    or not
  - push docker image IF a new version is being released

  ## how
  - use semantic-release plugin 'semantic-release-export-data' to store
    output in github actions whether a new version will be release ornot.
    - semantic-release plugin semantic-release-export-data will write
      output to github on whether a new version will be released. if a
      new version is being released, the tagname of the release version
  - set NEXT_VERSION env depending if semantic-release will be released
    or not
    - if there's NO new version, set NEXT_VERSION to the latest git tag
    - if there's a NEW version, set NEXT_VERSION to the new release
      version
  - push docker image IF a new version is being released
    - semantic-release will set an output to github-action to determine
      a new version will be released.

  ## why
  - eliminates one job
  - the entire process of extracting next release version is complicated
    and can go wrong
  - using 'semantic-release-export-data' plugin makes it easier
    extracting whether there's a new release and the new release version
