[bug\_fix] go: module /v2: go.mod file indicates module

Update the go.mod file of the dependency to declare its module path as '/v2', or downgrade the import to a v1 version if v2 isn't properly configured as a Go module.

Journey Context:
A developer tries to import a v2 package by appending '/v2' to the import path, adhering to the semantic import versioning rule. However, the build fails, claiming the go.mod file contradicts the import path. The developer is confused because they are following the Go module versioning rules perfectly on the consumer side. The root cause is that the author of the v2 dependency didn't update their go.mod file to include the '/v2' suffix in the module directive; they just tagged v2.0.0 in git. The Go toolchain strictly enforces that the import path must match the module directive in go.mod. The fix works by correcting the dependency's go.mod \(if the developer owns it\) to match the required major version suffix, ensuring the module's declared identity matches how it is imported.
