Add Release workflow for Codex

[veaceslavdoina]

As a part of the Testnet launch we should publish early releases and it is required to prepare a releasee workflow for GitHub Actions.

We already discussed some options

1. softprops/action-gh-release
   • https://github.com/status-im/nimbus-eth2/blob/stable/.github/workflows/release.yml
2. googleapis/release-please-action
   • chore(master): release 4.0.0 ethersphere/bee-js#674
   • https://github.com/ethersphere/bee-js/releases/tag/v4.0.0
3. ncipollo/release-action
4. release-drafter/release-drafter
5. marvinpinto/action-automatic-releases

We also should consider results from the Branch for testnet #747.

After release we also should publish releases for supported architectures/platforms and GitHub support is the following

OS/Architecture	amd64	arm64
Linux	ubuntu-22.04	public beta
Windows	windows-2022	public beta
macOS	macos-13	macos-14

• We may consider to use BuildJet for Linux arm64 builds.
• We may consider to use self-hosted runners for Windows arm64 builds

We may use different patterns for binaries names

# app-os-arch
codex-linux-x86_64
codex-linux-aarch64
codex-darwin-x86_64
codex-darwin-aarch64
codex-windows-x86_64
codex-windows-aarch64

# app-ver-os-arch
codex-linux-v1.0.0-x86_64
codex-linux-v1.0.0-aarch64
codex-darwin-v1.0.0-x86_64
codex-darwin-v1.0.0-aarch64
codex-windows-v1.0.0-x86_64
codex-windows-v1.0.0-aarch64

Note: We also can pack binaries with tar.gz, zip, etc.

That can be also useful to get release based on the OS/Arch

# v1.0.0
curl -L https://github.com/codex-storage/nim-codex/releases/download/v1.0.0/codex-`uname -s`-`uname -m` \
  -o /usr/local/bin/codex

# latest
curl -L https://github.com/codex-storage/nim-codex/releases/latest/download/codex-`uname -s`-`uname -m` \
  -o /usr/local/bin/codex

OS	amd64	arm64
Linux	Linux-x86_64	Linux-aarch64
macOS	Darwin-x86_64	Darwin-arm64
Windows	Windows_NT-AMD64	Windows_NT-ARM64

• Linux/Mac:echo "`uname -s`-`uname -m`"
• Windows: echo %OS%-%PROCESSOR_ARCHITECTURE%

It was decided to start easy and we use very simple release configuration using softprops/action-gh-release action.

Key point are following

• Use all free available architectures on GitHub Actions
• For Linux ARM use BuildJet
• Include version in the binaries names
• Pack binaries to minimize the size
• Experimenting with the uploading binaries to the Codex Testnet nodes
