fix(remix-dev/vite): remove http2 pseudo headers from internal request

[hi-ogawa]

Closes: #7867

I'm thinking this PR could help as a short term workaround for @remix-run/web-fetch Headers validation error.
This might not be a mandatory since there is a simple user side workaround by setting server: { proxy: {} } in vite config.

Also as I wrote in #7867 (comment), the removal of @remix-run/web-fetch polyfill would also make this workaround obsolete, so if remix team has a plan to remove automatic polyfills for newer node versions (this could be related? #7823), then this change will not be necessary.

Please let me know if there's any concern with this approach.

Testing Strategy:

I verified the same patch fixes my reproduction hi-ogawa/remix-reproduction-7867#2
