feat: added support for multi-platform builds

[chrheg]

This pull request includes updates to the .github/workflows/release.yml file to improve the release process by adding support for multiple platforms and setting up QEMU.

Platform support improvements:

• .github/workflows/release.yml: Added linux/arm64 to the platforms configuration to support ARM architecture.

QEMU setup:

• .github/workflows/release.yml: Added a step to set up QEMU using docker/setup-qemu-action to enable multi-platform builds.

Reason:

• Switching to arm64 runners from amd64 can result in approximately 37.5% savings in runner cost, which can lead to substantial cost reductions for larger organizations
