fix(deps): move off the yanked chacha20 0.10.1 (#6768)

chacha20 0.10.1 was yanked on crates.io today, which fails the Cargo Deny gate (error[yanked]) on every branch. cargo update -p chacha20 to 0.10.2; no API change, all dependents are semver-compatible.

Verification: cargo check -p rustfs-crypto; the Cargo Deny job on this PR is the authoritative gate.
