feature: add support for hostAliases

[kfess]

What type of PR is this?

/kind feature

What this PR does / why we need it:

This PR adds support for converting Docker Compose's extra_hosts field to Kubernetes' hostAliases field in Pod specifications.

When a docker-compose.yaml file contains extra_hosts entries, Kompose will now automatically convert them to the equivalent Kubernetes hostAliases configuration. This allows users to maintain custom host-to-IP mappings when migrating from Docker Compose to Kubernetes.

Which issue(s) this PR fixes:

Fixes #2066

Special notes for your reviewer:

• The conversion logic maps each extra_hosts entry (format: "hostname:ip") to a corresponding hostAliases entry with the IP and hostname
• Added unit tests to verify the conversion behavior
