Groovy DSL: Cannot set theme option

[Andraž Pajtler]

🐛 Describe the bug

Attempting to configure the theme option in Groovy DSL results in an error, whereas setting other options like orientation or linkText does not cause any issues.

⚠️ Current behavior

Build fails with error message: Cannot set the value of extension 'moduleGraphConfig' property 'theme' of type dev.iurysouza.modulegraph.Theme using an instance of type java.lang.Class.

✅ Expected behavior

theme can be configured.

💣 Steps to reproduce

import dev.iurysouza.modulegraph.Theme

moduleGraphConfig {
    readmePath = "./README.md"
    heading = '### Dependency Diagram'
    theme = Theme.DEFAULT
}
