Headers lost in fetch request when using BUN

[ryou90]

Description

To make Openapi-Fetch more compatible with Bun, the fetch call should be modified.
The problem is that Bun removes all header information within the request object.
To avoid this problem, the headers should be passed as extra parameters and not within the request object.

Current behavior :

let response = await fetch(request);

Suggestion:

let response = await fetch(request, {headers : headers});

Reproduction
Create simple Get request with header informations.

Expected result

Headers send with request
