[bug\_fix] go: [email protected]: invalid version: should be v0 or v1, not v2

Append the major version suffix to the module path in go.mod \(e.g., module example.com/pkg/v2\) and tag the release accordingly.

Journey Context:
A developer tries to tag and push a new major version of their library as v2.0.0 without changing the module path in go.mod. When consumers try to go get it, they get an error saying the version is invalid. The developer might delete the git tag and recreate it, or try to force push, confused about why Go rejects the tag. The root cause is Go's strict adherence to Semantic Import Versioning: a module whose path lacks a major version suffix is assumed to be v0 or v1. Tagging it as v2 without updating the path violates this rule. The fix works because updating the module directive in go.mod to include /v2 explicitly declares it as a v2 module, allowing Go to correctly map the v2.0.0 tag to the /v2 module path.
