reqwest 0.12.5 introduced rustls dependency on users of "http2" + "native-tls"

[talagrand]

When compiling reqwest with default features, or with:
default-features = false, features= ["http2", "native-tls"]

hyper-rustls is introduced as a dependency, which brings in rustls.
This may have been introduced by #2315

We're striving to avoid additional crypto dependencies, so this is problematic from a dependency analysis perspective.

This is a duplicate of #2320.
