Support typed bool, int and float in shortcode params

This means that you now can do:

    {{< vidur 9KvBeKu false true 32 3.14 >}}

And the boolean and numeric values will be converted to `bool`, `int` and `float64`.

If you want these to be  strings, they must be quoted:

    {{< vidur 9KvBeKu "false" "true" "32" "3.14" >}}

Fixes #6371
