Report #58792

[bug\_fix] module github.com/foo/[email protected] found, but does not contain package github.com/foo/bar

Update the import path in Go source files to include the major version suffix \(e.g., github.com/foo/bar/v2\) as dictated by the module's go.mod.

Journey Context:
A developer wants to upgrade a dependency from v1 to v2. They run go get github.com/foo/[email protected], and go.mod updates successfully. However, go build fails with 'module found, but does not contain package'. They are confused because the module was clearly downloaded. They inspect the dependency's go.mod and see module github.com/foo/bar/v2. According to Go's semantic import versioning rule, any module with a major version of 2 or higher MUST include the major version in the module path. The developer updates all their import statements from import "github.com/foo/bar" to import "github.com/foo/bar/v2", and the build succeeds.
