Update Sentry CLI from 3.3.3 to 3.4.0

[github-actions]

https://github.com/getsentry/sentry-cli/releases/tag/3.4.0

Features

• (snapshots) Add --selective flag to build snapshots to indicate the upload contains only a subset of images (#3268)
• (bundle-jvm) Allow running directly on a project root (including multi-module repos) by automatically collecting only JVM source files (.java, .kt, .scala, .groovy), respecting .gitignore, and excluding common build output directories (#3260)
• (bundle-jvm) Add --exclude option for custom glob patterns to exclude files/directories from source collection (#3260)

Performance

• (snapshots) Parallelize image hashing with rayon (#3250)

Fixes

• (snapshots) Chunk image uploads to avoid file descriptor exhaustion and 413 errors when uploading hundreds of images (#3249)
• (snapshots) Preserve subdirectory structure in snapshot manifest keys instead of flattening to bare filenames (#3269)
• Replace eprintln! with log::info! for progress bar completion messages when the progress bar is disabled (e.g. in CI). This avoids spurious stderr output that some CI systems treat as errors (#3223).
