http2 support tracker

[pi0]

there is not a direct thing we can do with ofetch to support http2 since ofetch depends on native runtime fetch as a wrapper but here are trackers:

• Node.js - undici (fetch support for HTTP/2 by default nodejs/undici#2750)
• Bun (Implement http2 support for fetch oven-sh/bun#7194)
• Deno (already enabled?!) (http2 support tracker #420)

Do you have any idea how complicated would be to replace undici vs native fetch in ofetch ?

h2 support was added in undici at version 5.24.0 here: https://github.com/nodejs/undici/releases/tag/v5.24.0
We are now 6.19.3 if I'm not mistaken native fetch leverage undici behind

Your first checkbox Node.js - undici would definitely solve everything ofetch wise though without having to change anything.

We are already partially pre bundling undici (via node-fetch-native) for proxy support and in next major it is gonna be merged. Honestly i prefer to avoid doing this and wait for Node.js stable releases bundle a known stable version of undici (for proxy and h2 aupport) but lets see how long it takes.
