[BUG] Incorrect image latest version

[oGi4i]

Describe the bug
Incorrect version is picked as latest.

To Reproduce
Steps to reproduce the behavior:

1. Deploy container with image docker.io/bitnami/redis with annotation match-regex.version-checker.io/redis: ^7\.\d+\.\d+-debian-\d+-r\d+$
2. The actual metric is:

version_checker_is_latest_version{container="redis",container_type="container",current_version="7.4.0-debian-12-r4",image="mirror.gcr.io/bitnami/redis",latest_version="7.2.5-debian-12-r4",namespace="cloud",pod="nextcloud-redis-master-0"} 1

4. The expected metricshould be:

version_checker_is_latest_version{container="redis",container_type="container",current_version="7.4.0-debian-12-r4",image="mirror.gcr.io/bitnami/redis",latest_version="7.4.0-debian-12-r4",namespace="cloud",pod="nextcloud-redis-master-0"} 1

Expected behavior
Semver version comparison has precedence over metadata version comparison.

Environment (please complete the following information):

• Version-Checker: 0.8.0+
• Kubernetes: 1.27.16
• Grafana: 11.2.0
• Prometheus: 2.54.1

Additional context
The root cause of the bug is here - there is metadata version comparison going on always if the current version is NOT less than the compared version. We should do metadata version comparison only if current semver and compared are equal.
