fix(ci): add Go, TinyGo setup to release workflow

[pcfreak30]

The Release workflow (release.yml) runs pnpm build which triggers build:wasm via turbo, but was missing Go/TinyGo setup and contract type generation. These steps exist in build.yml but were never copied to release.yml, causing sh: 1: tinygo: not found during release builds.

Added:

• actions/setup-go@v5 (Go 1.24)
• acifani/setup-tinygo@v2 (TinyGo 0.36.0)
• TinyGo env vars (TINYGOROOT, TINYGOPATH)
• Contract type generation (pnpm --filter=@lumeweb/lbry-sdk generate)

---

What changed
Updated the release workflow (.github/workflows/release.yml) so the release job can build the parts of the project that depend on Go/TinyGo:

• Added a step to install Go 1.24.
• Added a step to install TinyGo 0.36.0.
• Added environment variables for TINYGOROOT and TINYGOPATH.
• Added a step to generate contract types with pnpm --filter=@lumeweb/lbry-sdk generate before the main build step.

Why
The release build requires TinyGo-based generation to run, but the workflow was missing the Go/TinyGo toolchain setup. This change ensures the release job can fully build and publish the project.
