fix: Patch RUSTSEC-2026-0049 by removing legacy rustls-webpki 0.101.7 (#1919)

* Update `rustls-webpki` from 1.103.7 to 1.103.10 (the patched version
that resolves the linked vulnarability).
* Remove the older `rustls-webpki` dependency and a bunch of other
duplicates by listing `aws-sdk-s3` features explicitly.
