test: [skip e2e] optimize get_image_tag_by_short_name function (milvu…

…s-io#33780)

Refactor the function to improve performance and readability. Instead of
making API requests to Docker Hub, the function now retrieves tags from
the Harbor registry. It also filters the tags based on the provided
architecture and selects the latest tag that matches the prefix. This
change enhances the efficiency of retrieving image tags by short name.
