Grafana GO module: Grafana binary reports `(devel)` instead of release version in Go module metadata for `github.com/grafana/grafana`

### What happened? When inspecting the grafana-cli binary from the official Docker image `grafana/grafana:12.1.2`, the Go module version shows as `(devel)` instead of the expected tagged version `v12.1.2`. ### Possible Cause This typically happens when: - The binary was built from a development (non-tagged) state of the Grafana repository. - The source code used during the build was a local or “dirty” checkout without a clean semver tag. - The Go build toolchain could not determine a tagged version, so it defaults to (devel) to indicate a development snapshot. ### Impact This affects: - Automated tools and scanners that rely on Go build metadata to detect exact binary versions. - Security and compliance pipelines validating binary provenance. - Version traceability between released Docker images and their corresponding source code tags. ### What did you expect to happen? The released Docker image should include binaries built from a tagged commit corresponding to the published version (e.g., `v12.1.2`), allowing `go version -m` to report the correct module version. **Actual Result** ```sh grafana-cli: go1.24.6 path github.com/grafana/grafana/pkg/cmd/grafana-cli mod github.com/grafana/grafana (devel) ``` **Expected Result** ```sh grafana-cli: go1.24.6 path github.com/grafana/grafana/pkg/cmd/grafana-cli mod github.com/grafana/grafana v12.1.2 ``` ### Did this work before? With before versions of grafana images, the version was incorrect, which was having pseudo-versions. Issue was reported for that https://github.com/grafana/grafana/issues/106728 ### How do we reproduce it? 1. Pull the official Docker image: ```bash docker pull grafana/grafana:12.1.2 ``` 2. Create a temporary container: `docker create --name temp-grafana grafana/grafana:12.1.2` 3. Copy the grafana-cli binary from the container to your host: ```sh docker cp temp-grafana:/usr/share/grafana/bin/grafana-cli ./grafana-cli chmod +x grafana-cli ``` 4. In…
