[bug\_fix] go: @: invalid version: unknown revision

Push the missing Git tag to the remote repository, or use a pseudo-version \(e.g., \`v0.0.0-20231025152300-abcdef123456\`\) if pointing to an untagged commit. Ensure the version follows Semantic Versioning.

Journey Context:
A developer creates a shared library, tags it \`v1.0.0\` in Git, and pushes the commit. They then try to use it in another project via \`go get github.com/user/[email protected]\`, but get 'unknown revision'. They verify the tag exists locally. The rabbit hole involves checking Go proxy status, waiting for the proxy to update, and eventually realizing they forgot to \`git push origin v1.0.0\` \(they only pushed the commit, not the tag\). Alternatively, they might have tried to use a non-semver tag like \`1.0\` or \`release-1\`, which the Go toolchain strictly rejects as an invalid version. The fix works because pushing the valid semver tag makes it available to the Go toolchain \(and the Go Module Proxy\), allowing the version resolver to map the requested version string to a specific commit hash.
