Steps to reproduce

• Installed Spring boot Camunda 7.13.2
• Create a DTO with boolean primitive type field say "foo" and provide isFoo() instead of getter method.

  public class MyDTO {
  
    private boolean foo;
  
    public boolean isFoo() {
      return foo;
    }
  
    public void setFoo(boolean foo) {
      this.foo = foo;
    }
  
  }
  

• Create a sample DMN which takes this boolean variable as input. For example: myDTO.foo
• Now, set the value of MyDTO#foo to say true and evaluate the DMN table.
  A sample code for quick reference: camunda-example-drg.zip

Observed behaviour
The attribute foo does not exist in the context.

Expected behaviour
The attribute foo exists in the context.

Hints

• In https://github.com/camunda/feel-scala/blob/master/src/main/scala/org/camunda/feel/impl/interpreter/ObjectContext.scala#L30-L43, logic is written only to handle getters.
• This issue is first noticed while using Lombok jar. With Lombok, when DTO containing boolean primitive type field is compiled, it contains isFoo() method not the getter.
