chore(deps): update all dependencies to latest

[bryantbiggs]

Takes every Rust crate, GitHub Action and Terraform example dependency to its current latest.

• aws-sdk-autoscaling 1.130 → 1.135
• aws-sdk-ec2 1.254 → 1.268
• aws-sdk-eks 1.147 → 1.154
• aws-sdk-servicequotas 1.111 → 1.116
• rust-embed 8.12 → 8.13
• schemars 1.2.2 → 1.2.3
• Cargo.lock regenerated from scratch (tokio 1.53.3, rustls 0.23.46, hyper 1.12.0, serde_json 1.0.154 and others)
• actions/download-artifact v8.0.1 → v8.0.2
• actions/upload-artifact v7.0.1 → v7.0.2
• orhun/git-cliff-action v4.9.0 → v4.9.1
• dtolnay/rust-toolchain master 02cb101 → 683b588
• terraform-aws-modules/eks/aws ~> 21.25 → ~> 21.29
• terraform-aws-modules/vpc/aws ~> 6.0 → ~> 6.7
• hashicorp/aws >= 6.63 → >= 6.69

psm stays at 0.1.24 because pest 2.9.4 pins it exactly, and smallvec stays below 1.16 because serde-saphyr 0.0.29 caps it. k8s-openapi 0.28.0, kube 4.2.0 and gavinbunney/kubectl 1.19.0 are already latest.

Local gate: nightly fmt, clippy -D warnings, cargo test --all and xtask generate-all --check pass. terraform validate could not start providers in the local sandbox, so the terraform CI job is the check for the examples.

Supersedes #196, #197.
