Failure to build with go1.23 and above

[sudhackar]

$ go version && go build
go version go1.24.0 linux/amd64
# github.com/rogpeppe/go-internal/testscript
./exe_go118.go:14:27: cannot use nopTestDeps{} (value of struct type nopTestDeps) as testing.testDeps value in argument to testing.MainStart: nopTestDeps does not implement testing.testDeps (missing method InitRuntimeCoverage)
(staging Source Store)

From https://pkg.go.dev/testing/internal/testdeps

It was added in go1.23.0

Just adding this passes the build
