Report #14040

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

Verify the package path matches the repository's directory structure, or update the required module version in go.mod to a version that contains the package.

Journey Context:
A developer imports \`github.com/prometheus/client\_golang/prometheus/promhttp\` and runs \`go build\`, but gets this error. They check GitHub and the directory clearly exists. They clear the module cache, delete go.sum, and try again, but it persists. They then inspect their go.mod and realize that another dependency requires an older version of \`client\_golang\` \(e.g., v0.9.0\), and Go's minimal version selection resolved to that older version. In v0.9.0, the \`promhttp\` package didn't exist. The fix is to explicitly require a newer version of the module in go.mod \(e.g., \`go get github.com/prometheus/client\[email protected]\`\), which upgrades the dependency to a version containing the desired package. Minimal version selection then uses this newer version, resolving the missing package.
