[bug\_fix] go: module github.com/google/[email protected] found, but does not contain package github.com/google/go-cloud/blob

Use go get on the specific sub-module path \(e.g., go get github.com/google/go-cloud/blob\) rather than the repository root, because the project uses a multi-module repository structure.

Journey Context:
A developer wants to use a specific package from a large open-source repository. They run go get github.com/google/go-cloud and add the import github.com/google/go-cloud/blob to their code. When they build, they get an error that the module was found but does not contain the package. They verify the package exists on GitHub, leading them to try updating the root module to the latest version or clearing the module cache. The issue persists. The root cause is that many large projects use a multi-module repository structure where sub-directories are independent Go modules with their own go.mod files. The root module does not contain the code for the blob package; instead, blob is its own module. The fix is to target the specific sub-module path in the go get command, which downloads the correct go.mod and source code for that specific package.
