docs: Copy the type parameters from a JvmOperation.
  
  <p>This function differs from {@link #copyAndFixTypeParameters(List, org.eclipse.xtext.common.types.JvmTypeParameterDeclarator)}
  and {@link #copyTypeParameters(List, org.eclipse.xtext.common.types.JvmTypeParameterDeclarator)}
  in the fact that the type parameters were already generated and fixed. The current function supper generic types by
  clone the types references with {@link #cloneWithTypeParametersAndProxies(JvmTypeReference, JvmExecutable)}.
  
  @param fromOperation the operation from which the type parameters are copied.
  @param toOperation the operation that will receives the new type parameters.
