Spin 2.3.0

The 2.3.0 release of Spin brings a number of features, improvements and bug fixes.

Some highlights in 2.3.0 at a glance:

• Runtime upgraded to Wasmtime 18
• The Rust and Go SDKs have moved into their own repositories:
  • https://github.com/fermyon/spin-rust-sdk
  • https://github.com/fermyon/spin-go-sdk
• Multi-trigger improvements:
  • spin add can now add components with different trigger types (https://github.com/fermyon/spin/pull/2269)

cosign verify-blob \
    --signature spin.sig --certificate crt.pem \
    --certificate-identity https://github.com/fermyon/spin/.github/workflows/release.yml@refs/tags/v2.3.0 \
    --certificate-oidc-issuer https://token.actions.githubusercontent.com \
    --certificate-github-workflow-sha ee6706c8df54243c0689e648548217d142ff037a \
