[bug\_fix] go: ...: module ... declares its path as ... but was required as ...

Update the \`module\` directive in the dependency's \`go.mod\` file to include the major version suffix \(e.g., \`module github.com/foo/bar/v2\`\), and ensure all import paths in that module also use the \`/v2\` suffix.

Journey Context:
A developer creates a new major version \(v2.0.0\) of their library, pushes a git tag \`v2.0.0\`, and updates a client to use it via \`go get github.com/foo/bar/v2\`. The build fails, complaining that the module declares its path as \`github.com/foo/bar\` but was required as \`github.com/foo/bar/v2\`. The developer is puzzled because the git tag is correct. They discover Go's Semantic Import Versioning rule: for major versions v2 and above, the module path MUST include the major version suffix. The root cause is that the \`go.mod\` file in the v2 branch still says \`module github.com/foo/bar\`. Updating it to \`module github.com/foo/bar/v2\` and updating all internal imports within that module fixes the mismatch.
