Integrate Contributor interface and enable custom contributors in Maven publications

This pull request introduces the Contributor interface and its implementation ContributorImpl to provide more flexibility and customization for representing contributors in Maven publications compared to the existing MavenPomContributor.

Key improvements:

• Flexible contributor information: Define contributor details like name, email, URL, organization, roles, timezone, and optional custom properties using key-value pairs.
• Easier usage: Add contributors directly to the mavenPublish block like addContributor(TeogorContributor()).
• Kotlin data class: Leverages Kotlin data classes for concise and expressive contributor representation.

Example usage:

winds {
  mavenPublish {
    // Existing configuration...

    // Add a custom contributor (replace with your actual contributor):
    addContributor(TeogorContributor())
  }
}

TeogorContributor implementation:

This example TeogorContributor class demonstrates how to utilize the Contributor interface with pre-defined information:

data class TeogorContributor(
  override val name: String = "Teodor Grigor",
  override val email: String = "[email protected]",
  override val url: String = "[https://teogor.dev](https://teogor.dev)",
  override val roles: List<String> = listOf("Code Owner", "Developer", "Designer", "Maintainer"),
  override val timezone: String = "UTC+2",
  override val organization: String = "Teogor",
  override val organizationUrl: String = "[https://github.com/teogor](https://github.com/teogor)",
  override val properties: Map<String, String> = emptyMap(),
) : Contributor

Changes:

• This PR introduces the Contributor interface and its implementation ContributorImpl.
• Existing code using MavenPomContributor needs to be updated to use the new Contributor interface.

We believe this improvement enhances flexibility and maintainability for contributor management in Maven publications.
