HTTP 204 response header contains Content-Length value

[szgy]

Bug Report

Describe the bug
The http_prot.c (https://github.com/fluent/fluent-bit/blob/master/plugins/in_http/http_prot.c) line 73 contains this code:

flb_sds_printf(&out, "HTTP/1.1 204 No Content\r\n" "Server: Fluent Bit v%s\r\n" "%s" "Content-Length: 0\r\n\r\n", FLB_VERSION_STR, context->success_headers_str);

which is in contradiction with the RFC 9110 HTTP Semantics / Content Length :

A server MUST NOT send a Content-Length header field in any response with a status code of 1xx (Informational) or 204 (No Content). A server MUST NOT send a Content-Length header field in any 2xx (Successful) response to a CONNECT request (Section 9.3.6).
