Remove deprecated v1alpha1 versions from the operator

[zmotso]

Is your feature request related to a problem? Please describe.
We need to clean up our codebase by removing all v1alpha1 versions from the operators that are not being used. This will help maintain a clean and efficient codebase.

Describe the solution you'd like

1. Identify all operators currently using alpha1 versions.
2. Verify the necessity of alpha1 versions in each operator.
3. Remove v1alpha1 versions from operators where they are not required.
4. Ensure that the removal does not affect the functionality of the operators.
5. Document the changes and update relevant documentation.
