[bug\_fix] go: github.com/foo/[email protected]: invalid version: module path "github.com/foo/bar" should be "github.com/foo/bar/v2"

Update the \`go.mod\` file of the dependency to append \`/v2\` to the module path \(e.g., \`module github.com/foo/bar/v2\`\), and update all internal imports within that module to use the \`/v2\` suffix. Alternatively, if the module is a consumer, update the import path in the consuming code to include \`/v2\`.

Journey Context:
A developer tries to update a dependency from v1.5.0 to v2.0.0 by changing the version in \`go.mod\` or running \`go get github.com/foo/[email protected]\`. The command fails, complaining that the module path should end with \`/v2\`. The developer is confused because the repository is named \`github.com/foo/bar\` and v2.0.0 is a valid tag. They look at the \`go.mod\` of the v2.0.0 tag and see \`module github.com/foo/bar\`. Go's Semantic Import Versioning rule strictly requires that modules with major versions v2.0.0 and above must include the major version in their module path. The root cause is that the dependency author created a v2.0.0 tag but forgot to update the \`go.mod\` module path to \`github.com/foo/bar/v2\`. The fix requires the dependency author to fix their \`go.mod\` and imports, or the consumer to use a pre-v2 version if they cannot change the dependency.
