* Prevent Unnecessary Version Bumps in `go.mod` During Go Version Updates
This PR addresses issue #20770, where the minikube automation (triggered by make `update-golang-version`) unnecessarily bumped minor or patch versions in `go.mod` when updating the Go version. Following Kubernetes' practice, which avoids such bumps in `go.mod`, this change ensures only the go directive is updated to the stable Go version.
**Changes:**
- Added `go.mod` to the schema map in `hack/update/golang_version/update_golang_version.go` with a regex (go 1\.\d+\.\d+) to update the go directive to {{.StableVersion}} (e.g., go 1.24.2).
- This ensures the automation updates only the go directive without modifying module dependencies, aligning with Kubernetes' `go.mod` behavior.
**Impact:**
- Running make `update-golang-version` now updates the go directive (e.g., from go 1.22.3 to go 1.24.2) without unintended dependency version bumps.
- Tested by setting go 1.22.3 in go.mod, running go mod tidy and make update-golang-version, and verifying only the go directive and toolchain changed.
fixes: #20773
* Pin `go.mod` to Major.Minor Go Version (e.g., `1.24.0`)
**Description**:
Fixes#20773 by updating the automation to pin the `go` directive in `go.mod` to the major.minor Go version (e.g., `1.24.0`) instead of the full version (e.g., `1.24.2`), aligning with Kubernetes’ `go.mod`. This prevents breaking users relying on minikube packages.
**Changes**:
- Modified `hack/update/golang_version/update_golang_version.go` to compute `MajorMinor` version (e.g., `1.24.0`) from `StableVersion`.
- Updated `schema` to set `go.mod`’s `go` directive to `{{.MajorMinor}}`.
- Tested by setting `go 1.23.4`, running `make update-golang-version`, and verifying `go 1.24.0` with no dependency bumps.
**Closes**: #20773
