Add dependencies to exec-maven-plugin patch-gradle-props execution

Include explicit dependencies in the exec-maven-plugin execution. This should
ensure that required artifacts such as python-launcher are available when the
plugin runs this execution. This change should improve reliability of the
plugin execution, especially in environments where transitive dependencies
might not be available by default.
