Specifying exec fn that starts with hyphen is treated as option

``` clojure
:extract-select {:extra-deps {org.babashka/cli {:mvn/version "0.8.66"}}
                   :main-opts ["-m" "babashka.cli.exec" "dimigi.extraction" "-main"]}
```

Current workaround for this is to specify `"dimigi.extraction/-main"
