output string which contains not is incorrectly transformed

[nesies]

Describe the bug

task output with a value container "not" is wrongly converted to "not" expression

Steps to reproduce

create a Task whichn set a output string containing not:

 <bpmn:task id="Activity_1j6t5uw" name="set var2 str">
      <bpmn:extensionElements>
        <camunda:inputOutput>
          <camunda:outputParameter name="var2">${ "result is not ok" }</camunda:outputParameter>
        </camunda:inputOutput>
      </bpmn:extensionElements>
      <bpmn:incoming>Flow_1yiy9op</bpmn:incoming>
      <bpmn:outgoing>Flow_1x9vzzk</bpmn:outgoing>
    </bpmn:task>

The convert script wrongly converted the string:

      <bpmn:extensionElements>
        <conversion:message severity="REVIEW">Element 'outputParameter' was transformed. Parameter 'var2': Please review transformed expression: '${ "result is not ok" }' -&gt; '="result is not(ok")'.</conversion:message>
        <zeebe:ioMapping>
          <zeebe:output source="=&quot;result is not(ok&quot;)" target="var2"/>
        </zeebe:ioMapping>
      </bpmn:extensionElements>
      <bpmn:incoming>Flow_1yiy9op</bpmn:incoming>
      <bpmn:outgoing>Flow_1x9vzzk</bpmn:outgoing>
    </bpmn:task>

Expected Behaviour

          <zeebe:output source="=&quot;result is not ok&quot;" target="var2"/>

@nesies as the expression transformer works using regex, this can actually happen.

Therefore, the converter will always display you with a TASK to review the converted expression.
