Describe the Issue

I read Introducing support for server-sent events in Postman with excitement. But I can not use the endpoint written in python FastAPI framework.

Most web frameworks, including FastAPI (version 0.92.0), can include charset parameter in the Content-Type header.
The response header of the FastAPI endpoint have the charset parameter.

In the response HTTP headers, look for the Content-Type header, and in particular for the charset parameter, e.g.

Content-Type: text/event-stream; charset=utf-8

See the curl command using my local endpoint and the HTTP Response:

curl -v '127.0.0.1:8000/stream'
*   Trying 127.0.0.1:8000...
* Connected to 127.0.0.1 (127.0.0.1) port 8000 (#0)
> GET /stream HTTP/1.1
> Host: 127.0.0.1:8000
> User-Agent: curl/7.81.0
> Accept: */*
> 
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK

< server: uvicorn
< cache-control: no-cache
< connection: keep-alive
< x-accel-buffering: no
< content-type: text/event-stream; charset=utf-8   <- This is inserted by FastAPI EventSourceResponse
< Transfer-Encoding: chunked
< 
id: 1
event: notification
data: message_content

id: 2
event: notification
data: message_content
...

Steps To Reproduce

You can use the following fastapi endpoint written in Python.
