fix: correct Linux ARM64 installation instructions in release notes (#24)

Fix formatting issues in the release notes where the Linux ARM64 (glibc)
and Linux ARM64 (musl) installation instructions were incorrectly ordered
and the glibc section was missing its code block.

Changes:
- Added proper code block for Linux ARM64 (glibc) with radar-agent-linux-arm64
- Fixed Linux ARM64 (musl) code block to show radar-agent-linux-arm64-musl
- Corrected the order to show glibc first, then musl
