`make test` is failing with `go: no such tool "covdata"`

[mathieu-benoit]

make test is failing with go: no such tool "covdata", we need to fix this.

Described here: golang/go#75031.

Got the error with 1.25.0 but still getting the same error with 1.25.1... not sure what I'm missing:

$ go version
go version go1.25.1 linux/amd64

$ make test
go vet ./...
go test ./... -cover -race
# github.com/score-spec/score-implementation-sample/cmd/score-implementation-sample
go: no such tool "covdata"
