[bug\_fix] go: module example.com/[email protected]: reading at revision v1.2.3: unknown revision v1.2.3

Push the Git tag \`v1.2.3\` to the remote repository. The root cause is that the \`go.mod\` file in a dependent project specifies a version that doesn't exist as a tag in the module's upstream repository, so the Go proxy cannot resolve it.

Journey Context:
A developer publishes a new version of their internal library by tagging it locally as \`v1.2.3\` and updates a downstream service to use it via \`go get example.com/[email protected]\`. The local build works fine because the tag exists in their local Git repository. However, when they push the downstream service, the CI pipeline fails with \`unknown revision v1.2.3\`. The developer spends time checking network access to the proxy and clearing the CI runner's module cache, assuming it's a caching issue. Finally, they check the remote repository and realize they forgot to push the new tag. They run \`git push --tags\` in the library repository. Once the tag is pushed, the Go module proxy can resolve the version, and the CI pipeline successfully builds the downstream service.
