HTTP3/QUIC Support

[deepal]

Is your feature request related to a problem? Please describe.
It would be amazing to see HTTP3 support, now that it's widely available via many CDNs, supported by Chrome by default, and being rolled out by Firefox at the time of the writing. Curl also has experimental support for HTTP3 if built from source.

I might be definitely too early to ask for HTTP3 support in postman given that Postman still doesn't even have the support for HTTP2 as per #2701. But thought of creating this issue to start the discussion.

Describe the solution you'd like
Use HTTP3 for requests if the server supports it.

Describe alternatives you've considered
There are not many Rest/HTTP clients out there that supports HTTP3, but curl has experimental support if built from source specifically.
