This PR follows the request https://github.com/lukin/keywind/issues/6#issuecomment-1060100072:

CI/CD pipeline would be great. Something that can package up the theme into an archive, then add it to github releases. Then it can easily be installed using the Keycloak Operator.

After build, the theme is zipped in a similar approach as https://github.com/Alfresco/alfresco-keycloak-theme/releases/tag/0.3.2

Giving permission to the pipeline: Navigate Git > Project > Settings > Actions > General and enable Workflow permissions = Read and write permissions.

In order to create a new release:

1. Navigate to https://github.com/lukin/keywind/releases
2. Select 'Release'
3. Create a new/draft release with:
   • Choose a tag: 0.0.1
   • Target: master
   • Release Title: v0.0.1

Important that tag and title matches.

I hope it helps, please let me know if the commit looks good for you.
