Fix validation in the CRD definition

[jeffgus]

The validation fails to work when the image string has more than one ":". The validation failed when I tried to pull the marklogic image from an internal registry runnong on port 5000.

Pull Request Overview

This PR fixes the validation logic for the MarkLogic CRD definition so that it correctly handles image strings with more than one ":" by parsing the version from the last colon-separated segment.

• The validation expression is updated to reference the last element of the image split array.
• The version extraction now concatenates parts from the final segment of the image string.

• [nitpick] Consider refactoring to extract the repeated self.image.split(':') call into a temporary variable or function to improve readability and maintainability of the validation expression.
