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

Set the GOPRIVATE environment variable to include the private repository domain \(e.g., \`export GOPRIVATE=github.com/user/\*\` or \`github.com/user/repo\`\) to bypass the public Go proxy.

Journey Context:
A developer publishes a new tag \`v1.2.3\` to a private GitHub repository and attempts to use it in another project via \`go get github.com/user/[email protected]\`. The command fails with 'unknown revision'. The developer verifies the tag exists in GitHub and that they have SSH access. They clear the module cache and try again, suspecting a caching bug. The rabbit hole continues as they check git credentials. The actual root cause is that by default, Go routes module fetches through the public proxy \(proxy.golang.org\). The public proxy cannot access the private repo and returns a 404, which the toolchain translates to 'unknown revision'. Setting \`GOPRIVATE\` works because it instructs the Go toolchain to fetch the module directly from the source VCS instead of the public proxy, using the developer's existing git credentials.
