Switch workflows from tracking 'patch/3.2.x' branch to 'main', and update Docker image tags from 'v3-2-0-rc3' to 'v3-3-0-preview'. This ensures the latest changes are correctly integrated and deployed.
Changed the target branch from 'main' to 'patch/3.2.x' in the workflow YAML files. Updated Docker image tags to specific version '3.2.0-rc3' for both elsa-server and elsa-studio.
This commit introduces two new GitHub Actions workflows: one for building and deploying the Elsa Server + Studio Docker image, and another for the Elsa Server Docker image. Both processes automate the build and push actions to Docker Hub using the latest ubuntu version and buildx for multi-platform support.
