govulncheck: build with go1.23

Since go1.23 has been released in Homebrew and govulncheck was build with go1.22 it cannot work anymore.

```
/opt/homebrew/Cellar/go/1.23.0/libexec/src/slices/iter.go:50:17: cannot range over seq (variable of type iter.Seq[E])
-: This application uses version go1.22 of the source-processing packages but runs version go1.23 of 'go list'. It may fail to process source files that rely on newer language features. If so, rebuild the application using a newer version of Go.

-: This application uses version go1.22 of the source-processing packages but runs version go1.23 of 'go list'. It may fail to process source files that rely on newer language features. If so, rebuild the application using a newer version of Go.
