[console] fix line splitting in --runBefore (#5700)

before

    ./joern --runBefore '//> using dep org.apache.commons:commons-exec:1.5.0
    //> using dep io.methvin:directory-watcher:0.19.1'

would fail because the version number for commons-exec would not end at
"1.5.0", but instead also include the whole second line.
