Update docker images

[jssblck]

Updates Docker image bases from bookworm to trixie, except for minio which got ported to alpine due to the fact that the MinIO team no longer provides a prebuilt OSS image (reference: minio/minio#21647).

Validated this works by running E2E tests:

E2E_DOCKER=true cargo test --package attune --test it --all-features --release
         Finished `release` profile [optimized] target(s) in 0.73s
          Running tests/it/main.rs (target/release/deps/it-4587cdde45d24684)

     running 2 tests
     test e2e_host ... ignored, because variable E2E_HOST not found
     test e2e_docker ... ok

     test result: ok. 1 passed; 0 failed; 1 ignored; 0 measured; 0 filtered out; finished in 36.34s

Pull request overview

This PR updates Docker base images across the project, upgrading Rust from version 1.89.0 to 1.91.0 and MinIO from RELEASE.2025-04-08T15-41-24Z-cpuv1 to RELEASE.2025-10-15T17-29-55Z. Since MinIO no longer provides prebuilt Docker images, the update includes building MinIO from source using a multi-stage Docker build.

Key Changes:

• Upgraded Rust base image to version 1.91.0
• Implemented custom MinIO Docker build from source using golang:1.24-alpine
• Modified entrypoint script to use /bin/sh instead of /bin/bash for Alpine compatibility
