Escaping (or actually unescaping) special characters in query parameters

### What are you generating using Kiota, clients or plugins?

API Client/SDK

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

Nuget tool

### Client library/SDK language

Python

### Describe the bug

I'm trying to obtain a Sharepoint download URL using the Microsoft Graph SDK. This requires requesting the field ` @microsoft.graph.downloadUrl` via the `select` parameter. This does not work since the character "@" is always url-encoded, with no apparent way to override this behavior (except opting out of the sdk).

### Expected behavior

There is a way to stop kiota from url-encoding "@".

### How to reproduce

```python
drive_item = (
await client.drives.by_drive_id(drive_id)
.items.by_drive_item_id(drive_item.id)
.get(
request_configuration=RequestConfiguration(
query_parameters=DriveItemItemRequestBuilder.DriveItemItemRequestBuilderGetQueryParameters(
select=[
"id",
"@microsoft.graph.downloadUrl",
"webUrl",
"name",
"size",
]
)
)
)
# Unfortunately we have to do this since kiota encodes the "@" which does not work
# .with_url(
# f"https://graph.microsoft.com/v1.0/drives/{drive_id}/items/{drive_item.id}?select=id,@microsoft.graph.downloadUrl"
# )
# .get()
)
```

Start by reproducing the Python SDK request shown in the issue and trace how the select query parameter is encoded, focusing on the @ character. Done means callers can request @microsoft.graph.downloadUrl without opting out of the SDK, with coverage for this behavior.
