remove unnecessary info in action result history

[ykeremy]

here's an example of a current action history:

[
{
   "action":{
      "action_type":"click",
      "description":null,
      "reasoning":"The user needs to submit a support request to resolve the issue with the job application submission flagged as bot traffic. The 'Submit a new support request' link with id 11 is the relevant element to click to access the support request form, as indicated by the previous successful action results and the current screenshot showing the Greenhouse support bot prompt.",
      "element_id":11,
      "file_url":null
   },
   "results":[
      {
         "success":false,
         "exception_type":"MissingElement",
         "exception_message":"Found no elements. Might be due to previous actions which removed this element. xpath=//*[@unique_id='11'] element_id=11",
         "data":null,
         "step_retry_number":0,
         "step_order":8,
         "javascript_triggered":false,
         "interacted_with_sibling":false,
         "interacted_with_parent":false
      }
   ]
},
{
   "action":{
      "action_type":"click",
      "description":null,
      "reasoning":"The user needs to submit a support request to resolve the issue with the job application submission flagged as bot traffic. The 'Get help' button with id 8 is the relevant element to click to access the support request form, as indicated by the current screenshot showing the Greenhouse support bot prompt.",
      "element_id":8,
      "file_url":null
   },
   "results":[
      {
         "success":true,
         "exception_type":null,
         "exception_message":null,
         "data":null,
         "step_retry_number":2,
         "step_order":8,
         "javascript_triggered":false,
         "interacted_with_sibling":false,
         "interacted_with_parent":false
      }
   ]
},
{
   "action":{
      "action_type":"input_text",
      "description":null,
      "reasoning":"The user needs to interact with the Greenhouse support bot to resolve the issue with the job application submission flagged as bot traffic.

The user will explain the situation and request assistance.",
      "element_id":44,
      "file_url":null
   },
   "results":[
      {
         "success":false,
         "exception_type":"Error",
         "exception_message":"Error: Node is not an <input>, <textarea> or <select> element",
         "data":null,
         "step_retry_number":0,
         "step_order":9,
         "javascript_triggered":false,
         "interacted_with_sibling":false,
         "interacted_with_parent":false
      }
   ]
}
]

1. let's remove null

2.         "javascript_triggered":false,
     "interacted_with_sibling":false,
     "interacted_with_parent":false
   

these are definitely useless so let's remove them

3. TBD: I'm not sure how important successful actions are - shall we remove?

4.         "step_retry_number":0,
     "step_order":9,
   

TBD: are these important at all?
