Bump sdk-internal Rust crate dependencies

Overview

util/RustSdk/rust/Cargo.toml pins bitwarden-crypto from bitwarden/sdk-internal by git rev; bump it periodically to track a bitwarden/clients release. RustSdk is Seeder test infrastructure (util/, not src/ production): it gives the C# Seeder field-level encryption (encrypt_string/decrypt_string/encrypt_fields) to produce cryptographically correct Protected Data for integration tests. EncryptPropertyAttribute drives which fields get encrypted.

NPM → git-rev mapping

Clients consume sdk-internal as npm (@bitwarden/sdk-internal, e.g. 0.2.0-main.841); the server pins a git rev. The .NNN suffix is an opaque counter from a private Azure publish task — not a GitHub Actions run_number, and it does not track main commits 1:1. Do not infer the SHA from a run number or timestamp; both pick the wrong commit (verified: 841→c5d5bba, 842→c9f9dba, 840→1e45444 — no time correlation). Read the commit the build bakes into the published WASM instead:
