test(sealos): e2e test for sealos

[cuisongliu]

This pull request introduces new jobs in the GitHub Actions workflows and includes several other improvements and fixes. The most important changes include adding new jobs to the CI workflows, updating commands to use the repository owner dynamically, and modifying the Makefile to streamline the testing process.

CI Workflow Enhancements:

• .github/workflows/push.yml: Added a new job (job1) to build and push images using sealos. This job includes steps for setting up Go, verifying sealos, building images, and pushing them to the repository.
• .github/workflows/test.yml: Added a new job (job2) similar to job1 in push.yml, which includes steps for checking out the code, setting up Go, verifying sealos, and building images.

Command Updates:

• .github/workflows/update_version_config.yml: Updated the command to use the dynamic repository owner for generating and building the operator image.

Makefile Improvements:

• Makefile: Simplified the test and e2e targets by removing unnecessary dependencies on manifests and generate. [1] [2]

Code Fixes:

• gen/gen.go: Added a condition to handle the "latest" version by setting it to "0.0.0" to avoid issues with version replacement in the Chart.yaml file.
