Fix deprecated groovy space assignment (#47)

* Fix deprecated groovy space assignment

For more information check the Gradle migration docs
https://docs.gradle.org/current/userguide/upgrading_version_8.html#groovy_space_assignment_syntax

This avoids warnings in the build of projects using this as an underlying plugin.

```
Space-assignment syntax in Groovy DSL has been deprecated.
```
