[bug\_fix] module ... found, but does not contain package ...

Verify the import path matches the package's actual location within the module, or update the dependency version in go.mod to a version that actually contains the sub-package.

Journey Context:
A developer tries to import a sub-package from a third-party module. The build fails with module ... found, but does not contain package ... The developer checks GitHub and sees the directory exists. They go down a rabbit hole of clearing the module cache and checking their network proxy. The root cause is often a version mismatch: the developer's go.mod is pinned to an older version of the module that didn't have the sub-package directory yet, or the module's go.mod path doesn't match the import path prefix. The fix is to update the dependency to a version that actually contains the sub-package using go get @latest, ensuring the local go.mod reflects a version of the repository where the directory exists.
