Make the Docker image with all plugins the default image

[anna-geller]

Feature description

The plan

1. Rename latest-full to latest so that all plugins are included in the default image displayed at the top in DockerHub

2. Rename the current latest to latest-no-plugins with no plugins included.

3. Adjust the CI/CD and release processes to use kestra/kestra:develop instead of kestra/kestra:develop-full. Add kestra/kestra:develop-no-plugins.

4. Adjust the CI/CD and release processes to use kestra/kestra:v0.18.0 instead of kestra/kestra:v0.18.0-full. Add kestra/kestra:v0.18.0-no-plugins

Impact

• [ ] Users who leverage the latest image will need to change the image in their deployment before upgrading to latest-no-plugins if they prefer to have only their custom plugins. We should make that Breaking Change very clear in the Release Notes
• [ ] Adjust all Getting Started and Installation docs afterward to use the kestra/kestra:latest instead of kestra/kestra:latest-full
• [ ] Adjust the main GitHub README
• [ ] Adjust Helm Charts README and deployment guides
• [ ] Adjust Zendesk guides to use that image

The same should be done for all tags: develop/develp-full and v0.18.0/v0.18.0-full (and all future version tags).
