Issue:
security mapping in getKiotaTree in npm package is not correct
### What are you generating using Kiota, clients or plugins?

Kiota plugin

### In what context or format are you using Kiota?

Npm package

### Client library/SDK language

None

### Describe the bug

When mapping from OpenAPI description a security requirement object does not return an array but a single object with a dictionary.

### Expected behavior

It should map into an array instead of single object

### How to reproduce

For example of below schema:
security:
  - api_key: []
  - petstore_auth:
	- write:pets
	- read:pets
 
It should produce security like below:

```code
"security": [
  {
	"api_key": []
  },
  {
	"petstore_auth": [
	  "write:pets",
	  "read:pets"
	]
  }
]
```
 
However, current getKiotaTree result is object:
```code
  {
	"path": "\\pet\\{petId}#GET",
	"segment": "GET",
	"children": [],
	"selected": true,
	"isOperation": true,
	"operationId": "getPetById",
	"summary": "Find pet by ID",
	"description": "Returns a single pet",
	"servers": [],
	"security": {
	  "api_key": [],
	  "petstore_auth": [
		"write:pets",
		"read:pets"
```
