Drop spdy in favor of node:http2

[talentlessguy]

Modification Proposal

Remove spdy and use node built-in http2 server. spdy is broken since node 16 (source. Perhaps node:http2 could be wrapped in a way that it would be compatible with express.

Expected Behavior / Situation

Usage of http2 in favor spdy. Support for http2 and deprecation of spdy.

Actual Behavior / Situation

Lack of http2 option and only support for spdy.

Please paste the results of npx webpack-cli info here, and mention other relevant information

We already support http2 out of box, but only for custom application (which support it), example for connect https://github.com/webpack/webpack-dev-server/tree/master/examples/server/http2

built-in http2 server

You can use pure http2 server using the server option like here https://github.com/webpack/webpack-dev-server/blob/master/examples/app/hono/webpack.config.js#L35C5-L35C11

spdy will removed in the next major release

Unfortunately express doesn't support http2, so it will not work
