notification filter ${BUTTON_FORM_DATA} hides button

[InternetPseudonym]

Currently, it is not possible to filter for ${BUTTON_FORM_DATA}, the button will not be shown on pull requests if ANY regex value is entered

how to reproduce :

• create a button with confirmation dialog and form :

[
  {
    "defaultValue": "FIRST",
    "description": "my description",
    "label": "choose one",
    "name": "myOption",
    "buttonFormElementOptionList": [
      {
        "label": "first option",
        "name": "FIRST"
      },
      {
        "label": "second option",
        "name": "SECOND"
      }
    ],
    "required": true,
    "type": "radio"
  }
]

• create a notification with filter string : ${BUTTON_FORM_DATA}, filter regex : anything

expected result : button is displayed on pull requests actual result : no button
